Faxing and machine-to-machine communications in the IP-based telephony age

The new direction for telephony

There is a new direction for telephony that will be affecting faxing and machine-to-machine communications over the next few years. It is Voice-over-IP which is regular voice telephony carried over an Internet-standard network.

This has been used primarily in large-business telephony but is now becoming a reality with consumers and small organisations. Initially, this technology was being pitched as a way of saving money on long-distance calls but is now becoming part of regular landline telephony.

The main drivers for this direction are the arrival of “naked DSL” Internet services where the telephone wires are used for DSL Internet connection and the customer doesn’t pay the incumbent telephone company for landline telephone service; cable-TV providers stepping to the fore for providing competitive local telephony service; and and the arrival of “single-pipe triple-play” services with multi-channel TV, Internet service and landline telephony delivered over one physical connection as one service package. These services are using the VoIP telephony technology to provide the local landline telephone service.

The next driver that will affect all customers is the national landline telephone system being moved away from the traditional circuit-driven setup to a packet-driven Internet-technology setup. Examples of this are the 21CN project in the United Kingdom and the National Broadband Network project in Australia. The advantage of these projects is to reduce the cost of providing regular voice telephony over short or long distances and to prepare for improved telephony setups like HD wideband voice telephony and video telephony. 

The effect on machine-to-machine applications

This will place a negative effect on machine-to-machine applications like faxing and monitored-alarm setups which are the two main applications that are facing consumers and small organisations. These setups are based on modem-based protocols that are designed for circuit-switched telephone networks like the “plain old telephone service”.

The main effect of this is that the packet-based telephony setups will cause the protocols used in these applications to go “out of step” and lead to communication failure. In the case of a fax machine, the document will either take a long time to go through to the correspondent or the fax transmission won’t succeed. In a monitored-alarm setup, the alarm event that is initiated by the premises-based alarm system will take a long time to register with the monitoring station or at worst won’t register there at all, which is a threat to security and safety – the main reason for these systems in the first place.

Bringing these applications to the IP age

Faxing

The T.37 Fax-over-email solution

Most high-end business-market fax machines are equipped to work according to the T.37 “fax-over-email” protocol. This is a “store-and-forward” method that uses regular SMTP and POP3 Internet email protocols to send hardcopy faxes as TIFF-F (fax-optimised TIFF) image files attached to emails.

This solution requires that the recipient has a T.37-compliant fax machine or computer which is running an email client and software for reading TIFF-F files to receive the files. This may be no mean feat for a general-purpose desktop or laptop computer hut most smartphones and similar devices won’t have software that can read TIFF-F files.  As well, a person can use a scanner attached to a general-purpose computer that has software that can turn out TIFF-F files from the scanner as well as the regular email client to send hardcopy documents to a T.37 fax machine.

Some T.37-compliant fax machines can be set up to work as a T.37 – G3 gateway to forward faxes to regular fax machines. But this requires the sender to send email to an address formatted as “fax-mailbox@service-domail(FAX#fax_number)”, which can be difficult with many popular email clients. Here, these clients may not handle the phone-number data that is held in parenthesis properly or require the user to “go through hoops” to support this function when they manage their address book. It may be easier if the gateway uses a “international-format-fax-number@fax-gateway.service-domain” address format.

As well, the technology could support colour or greyscale photographic images through the use of JPEG or a colour variant of TIFF-F. This point is raised because of most fax-enabled inkjet and colour-laser multi-function printers being equipped with the ability to send and receive colour faxes using the “Super G3” protocol.

The T.38 real-time-fax solution

The T.38 protocol has been introduced as a method of providing “there-and-then” fax transmission over an IP network. At the moment, it requires a gateway device to be connected to a regular fax machine at each end of the link. This could be achieved by the use of a properly-designed VoIP “analogue telephone adaptor” terminal that becomes a T.38 gateway when it is connected to a regular fax machine.

The standard also requires the use of SIP and other call-setup protocols that are used in VoIP to establish the call. The destination information would have to be understood by the gateway picking up the DTMF “touch-tones” from the connected fax machine.

You can use a single ATA for VoIP and T.38 service, with use of distinctive ring + CNG fax tone to “wake up” client fax for incoming calls and use of the CNG fax tone generated by the connected fax machine to enter T.38 mode. But this would require separate T.38 service with separate number to be provisioned for smooth operation.

Another question is whether a network-enabled fax machine can become a T.38 fax endpoint machine or not? As well, would the T.38 protocol support enhanced fax modes like “photo” resolution or colour faxing.

What can be done

Improved provisioning experience

At the moment, most mid-tier consumer and all business multifunction printers have regular fax functionality and network connectivity. As well, some small-business units, especially the units sold by Brother, have T.37 “fax-over-email” functionality as part of the function set.

Typically these features are difficult to provision and use for most home and small-business users. What could be done is to implement a “wizard-based” user experience for the provisioning routine and / or, there could be the ability to download an XML provisioning file from the Internet provider whenever one wants to set up Internet fax.

As well, the industry could adopt a qualification program for Internet-fax equipment that requires a unit to achieve certain requirements such as compliance with known standards before being able to receive the right to display a particular logo of compatibility. This could also extend to the use of service-information files provided by carriers and service providers so that there is little effort required on the behalf of the home or small-business customer to set up their Internet fax service.

Internet fax service as part of a communication service provider’s arsenal

As far as addresses for T.37 fax services go, there could be the ability for a subscriber to be provided with a “virtual fax number” as well as an email address for their T.37 service. This is a telephone number that a person can dial to send faxes to the T.37 mailbox from the regular fax machine. Similarly, there could be support for an SMTP fax-gateway setup that uses a simplified addressing scheme as I have outlined earlier but uses address and password protection to authenticate customers and these would then be related to the “virtual fax number” which is to show on a regular fax machine’s display and  in the fax transmission reports.

The T.38 real-time-fax service could simply be provided by a VoIP or triple-play communications provider as a secondary fax-only number which works with T.38-compliant fax gateways or endpoints. This could be provided with a T.37-compliant Internet fax mailbox that can lead to such services as controlled transmission or reception setups such as “receive all faxes when you start business” or “transmit international faxes I send on local morning time”.

Equipment and software design considerations

A network-enabled fax terminal should support both the T.37 and T.38 network-fax protocols as well as the Super G3 protocols for circuit-based communications. As well, the setup experience for these machines should be simplified, preferably wizard-driven and with service-host interaction, so that people who don’t have much computer experience can get these machines going for Internet fax. This can be augmented by support for standardised XML-based service-manifest files that are downloaded from the service host.

The same machines could also support the storage of fax addresses as regular numbers or Internet-format email addresses and could simplify the construction of Internet-based fax addresses for regular number-based addresses based on however the T.37 fax server expects such addresses to be formed. This should then simplify the management of the one-touch or speed-dial address book that is part of the typical fax machine’s feature set. As well, email software should support the ability to send and view T.37 fax-over-email messages and support “sub-addressing” and address construction for T.37 fax gateway servers.

Monitored alarms

The main method that is being used for adapting an existing  monitored alarm infrastructure to an IP-based environment is to use a VoIP analogue-telephony-adaptor terminal that is programmed to be a “virtual modem” endpoint. Here, the alarm uses the standard modem protocol to signal the event to the ATA and this device forwards the event message to the control centre using an industry-standard message packet.

On the other hand, a network-enabled alarm system could be connected to the network and sends the event message via its network interface. This also includes existing systems that are designed to be future-proof by allowing a network interface kit to be installed at a later date.

There will also be the desire to provide this kind of network integration to this class of device in order to support enhanced monitoring functionality or building automation. The latter application would bode well with the “green impetus” in order to provide functionality such as synchronised control of lighting and heating / air-conditioning.

Another benefit is that a monitored alarm setup can be upgraded with new firmware without the need for a technician to visit the installation. This is in the same way that computers and mobile phones can be “patched” with software fixes by them connecting to a server to get the necessary software.

What needs to happen

Customers need to know what to do concerning evolving their monitored security or safety services to the Internet-driven world and view it as being important for all such services, not just for high-perceived-risk installations. As well, any monitored-alarm equipment that is pitched at the residential or small-business user has to have inherent IP-based monitoring or have support for the feature at a later date.

Equipment design considerations

The alarm-system industry needs to provide panels that either have inherent support for IP-based  signalling or can be upgraded to this function at a minimal cost through its service life. This is understanding that a typical alarm installation is seen by its users as a “backbone” device in the same context as a central-heating boiler or furnace and is therefore expected to have a service life of at least 10 or more years.

This should mean that a hardware upgrade should be in the form of a card being installed in to the existing alarm panel or a software upgrade is provisioned by, at the most, one visit from a technician.

Conclusion

As telephony systems move towards the packet-driven IP telephony space, the traditional machine-to-machine applications that face most users need to be evolved to support the Internet-based networks. This includes improved in the way these services are set up so that most people can provision them in a competitive manner rather than being tied to a particular carrier or operator.

The Telstra T-Hub can now become a fully-fledged Internet radio

News article

Tune into the world with the latest T-Hub software update – Radio, Software, Global | Telstra Exchange

My comments

Previously, the Telstra T-Hub multipurpose Internet device had an Internet radio function but this was limited to receiving the Internet streams of Australian radio stations. Most of us would think that this is limiting because of radios like the ones reviewed on this site being able to pick up Internet streams from overseas radio stations or the fact that we could use vTuner or Reciva web sites to “tune in to” these streams.

There had been a lot of discussion about this on Telstra’s “Exchange” website especially as they were about to release new software for this device, especially with a desire to have this functionality on board. Now Telstra have answered these calls by integrating the fully-fledged Internet radio functionality in to the T-Hub as part of the latest (version 1.10k) firmware update.

Someone raised in response to this article an issue about whether the Internet-radio service would be counted towards one’s Internet-traffic limit and there is a fear that it may not be so for overseas stations. Another key issue that also has to be resolved would be the quality of service that one gets with Internet radio because, as from my experience, there are times where there is increased jitter and latency with Internet radio stations especially when the station’s home country or we enter peak Internet-use times.

This news is also of interest to manufacturers, distributors and users of other multipurpose Internet devices that are intended to supplant or supplement landline-telephone functionality.

How to update the T-Hub to the latest version

  1. Touch the “Settings” icon on the T-Hub’s second home screen
  2. Touch the “Software Updates” icon.
  3. Touch “Check for New Software Updates”. This will identify if the T-Hub is on the latest firmware or whether there is an available update.
  4. If an update is available, touch “Download Now” to start the update process.

The Wi-Fi Personal Area Network is getting closer

Ultra-Low-Power Wireless Networking

My comments and questions

Previously I have covered the topic of WiFi technology being used as a “personal area network” for a computer, which comprises of peripheral devices like mice and keyboards communicating to a particular computer via the WiFi technology. rather than that technology being used to transfer data between computers and other devices in a local area network. What has happened is that Ozmo have come up with a real chipset for use in these devices that can use this medium as well as run for a  long time on batteries. At the same time, Ozmo had built reference designs of wireless mice and keyboards that use this technology to communicate with their host devices.

One main question that I have about Ozmo’s effort is whether the same technology can be applied to devices that link directly to a Wi-Fi local area network’s access point rather than a particular computer? One main application that I see here with this technology would be Wi-Fi as a sensor / control network medium with devices like those that Ekahau had made as part of their Wi-Fi-driven real-time location technology, such as the pager tag which I had talked about in this site previously. Another application would be Internet radios, Wi-Fi-connected speakers and similar multimedia terminals that would be able to work on batteries as well as digital cameras that can upload to network storage or Internet sites or present to DLNA terminals without a severe penalty on battery life.

Another issue would be for a dedicated-function device like a set-top box or games console to support this kind of technology, whether as part of integrated Wi-Fi LAN functionality or as a Wi-Fi PAN setup as an alternative to Bluetooth or infra-red as a way of connecting peripherals, especially control peripherals.

It would be very interesting to see what comes of this technology once the silicon becomes fully available.

“Electronic hard copy” publishing – should this only be for the iPad platform?

Since the start of this year, there has been some interest shown by traditional hard-copy media publishers and book publishers in the idea of e-books and similar technologies. This has mainly been brought about by the arrival of devices like the Amazon Kindle and the Apple iPad. This concept has interested the newspaper and magazine publishers who have fund the value of their hard-copy titles dwindling as readers place more value on Web-hosted online news sources.

“Electronic hard copy” becoming only for the Apple iPad

This has intensified with the arrival of the Apple iPad where nearly every mainstream newspaper publisher is offering a subscription-based app for this platform and moving towards placing their online content behind a subscription-driven paywall, The biggest fear that I have about the current “electronic hard copy” situation is that all of the publishers will simply develop their “electronic hard copy” projects so that they only work with the Apple iPad.

Other platforms that exist

There are touch-based Internet-tablet platforms other than the iPad that can do the job of being an endpoint for “electronic hard copy” reading. The ones that come to mind are the Google Android platform which will be evolved into a touch-based Internet-tablet form factor as well as touch-enabled computers that run Microsoft’s Windows Vista or 7 operating systems. Infact I have viewed this site through a Hewlett-Packard TouchSmart “all-in-one” desktop PC at HP’s stand during the PMA Digital Life Expo yesterday in order to show a review of one of their products that was on the stand. This unit had the ability to “click on to” links at the touch of a finger or you could stroke your finger upwards to scroll through the site.

Similarly,there could be other touch-enabled Internet tablet platforms written for other embedded operating systems like Symbian, Bada or Maemo. As well, Microsoft can also provide a “scaled-down” distributions= of their Windows 7 codebase as the basis of a touch-enabled Internet-tablet device.

A common “electronic hard copy” distribution platform

What needs to happen is for the creation of a common “electronic hard copy” distribution that allows for the support of periodical content that is provided for free, “by the unit” or on a subscription basis in a similar manner to regular hard-copy periodicals. It should allow for authenticated distribution, rich-media content such as animation or video, search and interactivity amongst other things. It should also allow the publishers to “brand” their content and see a layout in a similar manner to how the hard-copy form has been presented.

For periodical content, technologies like the RSS Web-feed platform could be used as a basis for “pushing” newer issues to the device through the life of a subscription while there could be support for content-specific paradigms. In the case of comic-strip content, there could be the ability to scroll through each frame which would be variably-sized and perhaps may be accented with multimedia. Some material could allow for searching, filtered browsing and / or dynamic typesetting, such as a “full” dictionary that can be filtered down to provide words considered “legal” for Scrabble or a dictionary that emphasises in another colour “Scrabble-legal” words.

As well, you should be able to buy content for the device from anywhere other than the device’s “app store” like the way a Nokia phone user can get an app for their phone from the developer’s Web site, the Handango app store as well as the Nokia Ovi app store. This avoids the situations that have been occurring with Apple and the way they have been approving or disapproving apps for their iTunes App Store.

Conclusion

Once a common distribution platform exists for “electronic hard copy” content that works in a manner that breeds competitiveness, then more people would be able to benefit from this new way of distributing books, newspapers and magazines.

Hitachi-LG optical-reader / solid-state drive combo for laptops

My comments

The main thing that impressed me about this was that both the tray-load optical drive and the solid-state drive wore integrated in to the same low-profile chassis that would suit installation in to a laptop. There are many benefits that I see with this.

One would be that you could have a laptop specification that has both a large-capacity hard disk that is used for data and a lower-capacity solid-state drive used for the operating system and applications. It could then allow for battery economy and quick starts while the high capacity on the hard disk can exist for the user’s data and this hard disk is only spun up when the user’s files need to be loaded or saved.

As well, if Hitachi and LG move towards higher solid-state capacities, this could allow for low-profile laptops like the “thin-and-light” segment to have the SSD as the main system drive while supporting an optical drive.

Another one for the Android-based TV platform

Sony’s official Internet TV Website – Sony Style

My comments

Previously, I had written in my blog about People Of Lava introducing an Internet-enabled TV that was based on the Google Android Platform. This is a brand that may not be on everyone’s lips, especially when it comes to consumer electronics.

But now Google had determined an Android-based app-driven TV platform to go alongside their Android app-driven mobile phone platform and described it as “Google TV”. They have pitched this at digital TV sets and various set-top applications, primarily as an open platform for delivering Internet-enabled interactive TV.

Sony have become the first mainstream TV manufacturer to implement this platform, which will give it an air of legitimacy in the consumer-electronics space. This is eve though the interactive-TV space has been dominated by various closed or limited platforms like the games consoles, the PVR boxes such as TiVo, and various pay-TV platforms.

I often wonder that if Google keeps the Android platform as an open platform, they could provide many interesting applications and uses for many devices.

The first of the “netvertibles” or convertible netbooks – a possible challenge to the Apple iPad perhaps

News article

Acer launches 11.6-inch Aspire Timeline 1825PT netvertible – Engadget

My comments

This computer is becoming one of the first netbook-class notebook computers to have a multi-touch screen. The main problem with these machines is that consumers will forget about them because they are so entranced by Apple’s iPad.

If you want to make this class of netbook come up very well with consumers, you will have to provide touch-enabled book-reading applications for the main e-book and online-comic platforms to work with Windows and other “freely-programmable” operating systems. As well, machines like this Acer should use a “tilt-sensor” to determine the display orientation in order to provide a “broadsheet” or “tabloid” view.

As well, anyone who provides an “online newspaper” platform will need to make sure that people can subscribe to their papers from any platform as long as the appropriate reading software is in place and the software should be ported to many platforms like Windows, MacOS X and Android.

Then they could effectively challenge the iPad in providing an online reading platform for books or newspapers.

The HTML5 vs Flash debate

The computer press have been running articles regarding the use of Flash or HTML5 in highly-interactive Web sites such as video sites.

It has started off with Apple wanting to move iPhone and iPad towards HTML5 / H264 video by proscribing Flash runtime engines from these platforms and forcing developers to move to the HTML5 / H264 platform. This caused Google to write YouTube client-side apps for these platforms and develop an HTML5 site. Then Microsoft and others worked towards implementing HTML5 in their next browser issue, with some browsers being equipped with HTML5 interpreters.

The debate about HTML5 vs Flash has been more “video-centric” because Adobe Flash was mainly used by YouTube to display the many videos hosted on that site.

It is worth noting that the FLV files used in YouTube and similar Flash applications are container files with the video and audio encoded using the H.263 video codec. The HTML5-based video applications will use FLV, MOV or AVI container files with H.264 video codecs which are becoming the standard for high-resolution video.

Applications beyond video

Adobe Flash has been used for applications beyond video. Primarily it has been used for high-interactivity applications like games such as Farmville on Facebook or the casual games on MiniClip because it offers a quick-response user interface and easy development that these applications needed. Here, it has offered a “write-once run-anywhere” platform for these Web-centric applications with plenty of “rapid-application-development” tools.

It is also worth knowing that most of these games refer to back-end databases and / or “client-local” cookie files to persistently store game-state and other user-generated data. These programs will then have to work with the different data stores as they are used.

Web-based runtime environments for partially-linked programs

HTML5 has a variety of inherent elements that allow for vector-graphics and interactivity for highly-interactive applications. It also may be of benefit to open-source software developers and Linux advocates/

But there are some developers, most notably games developers, who want to keep their source-code closed in order to control reuse of that code. These developers also want to provide programs in a manner where the target machine doesn’t have to interpret or compile code before it is of use, which will benefit high-interactivity applications where quick response is desired.

These developers typically want to provide these programs as either an executable file or a “p-code” (partially-linked) program file which is run by an interpreter or just-in-time compiler program, known as a runtime module, that works with these files on the target platform. At the moment, there isn’t a mechanism for delivering a compiled HTML5 file in a “write once, run anywhere” manner.

Java

An interactive-applications developer could work with the latest version of Java to develop these kind of applications in a “write-once run-anywhere” platform. This platform is natively supported by the Blu-Ray Disc system as part of providing interactive video from discs and/or the Internet through that system. It could then lead to someone writing a games disc that runs classic games types on any old Blu-Ray Disc player without the player being a games console.

The main issue with this is that not all platforms, especially tablet and handheld platforms, support Java natively. As well, desktop support for Java may require the Java runtime software to be downloaded separately from Sun.

Microsoft Silverlight

As well, Microsoft is wanting to advance their Silverlight runtime platform for client-executed Web applications but this platform has not yet been ported for anything outside general-purpose computers running the Windows operating-system family. Again, this is another platform for Web-based highly-interactive content that requires the client machine to work with a “runtime module”.

Apple’s control over what runs on their platforms

One of the main cornerstones in this debate is what Apple wants out of the iPhone, iPad and iPod Touch platforms. They want to maintain control over programs and highly-interactive content that runs on this platform and preserve the requirement that all such content is obtained through the iTunes App Store. The practice of supplying a “runtime module” for pre-compiled “p-code” software available elsewhere, such as what happens with Java and Flash, works against this ideal because Apple can’t see the program’s code before it runs on an iPod or iPhone. Therefore Apple have proscribed the creation of such modules for this platform.

Some Apple skeptics may also have a fear that Apple may change their desktop platform away from the Macintosh (MacOS X) platform where their is a “free-for-all” for software development towards a platform not dissimilar to the iPhone or iPad platform with a controlled development environment. This is like how they retired the Apple II platform in the early 90s in order to focus on the Macintosh platform.

The open question

Therefore, there is an “open question” concerning Web-based software development. It is whether the likes of Farmville or Bejewelled should be developed using HTML5 and in a vulnerably-open manner or whether they should be packaged as “p-code” and delivered to a runtime environment? It also includes whether Apple should expect developers to create a separate client-side app for their iPhone / iPod / iPad devices for each game or highly-interactive site that they work on.

Arrival of e-paper-based sun-resistant displays for portable computer devices

News articles

Sonnenresistente Displays gehen in Massenproduktion – Der Standard (Austria – German language)

From the horse’s mouth

Pixel Qi – web site

My comments on this technology

If you have ever tried to use your laptop, mobile phone or digital camera outside on a bright sunny day, you will have found it very difficult to read the device’s screen in that bright sunlight. Some users may have fashioned up loupes or shades to force the sun away from the screen and others may have preferred to work in shady areas like under a tree or in a shadow.

Pixel Qi have designed a colour display which uses a combination of LCD and e-paper technology to avoid this washout problem. It has the advantage of the always-backlit standard colour LCD display but uses the e-paper technology to enable reflective viewing in brighter lighting environments. This has also allowed for the backlight to be used only as needed, thus saving power and allowing for a longer operating time when on battery power.

Some people may think that these advanced displays won’t work well with video or games but they have the same refresh rate as the current-generation standard LCD display thus will work properly with these applications.

At the moment, the only screen size that is being built with this technology is the 10.1” widescreen which will be pitched at e-book readers, netbooks, subnotebooks, tablet devices and high-end large-screen electronic picture frames. This is mainly because they are supplying this technology to the low-power laptops that are part of the “One Laptop Per Child” project. They are yet to make smaller and larger screens for the other display applications like standard laptops, regular electronic picture frames digital cameras or HDTVs.

What I am definitely pleased about with this technology is that there is a colour LCD display that is friendly to all lighting environments and can allow portable devices to run longer.

32GB MicroSDHC card from SanDisk – What could this provide

News articles

SanDisk flips out 32GB mobile phone card • The Register

My comments

Can your device handle 32GB or larger cards?

There may be issues with SDHC-compatible devices not handling cards that are 32Gb or larger. This may result in the device refusing to mount the card (make it accessible to its operating system for storage) or file-system activities may take a long time to complete.

This may be rectified through an operating system or firmware update for your computer or device. In the case of computers, it may be worth checking the online update program for drivers or middleware that can do this job. For devices such as smartphones, check for “field-deployable” firmware updates that can allow the device to properly work with large SD cards.

There may be a limitation with devices that don’t work with a field-update procedure for their firmware and, in some cases, the manufacturer may not revise the firmware at all through the device’s lifespan. These situations may limit your ability to work with the large cards and you may have to wait for newer models to come out to take advantage of them.

Use beyond smartphones

Achieving a small neat nice design for portable equipment without forfeiting capacity

The 32Gb MicroSDHC card may also yield a valid reason for camera manufacturers to implement MicroSD cards in smaller camera designs when they equip these devices with high-resolution still or video capabilities.

This could similarly benefit handheld audio equipment like “digital notetakers” and personal media players where there is a desire to store a high quantity of higher-quality recordings yet achieve a pocketable design.

Similarly, manufacturers could cram more circuitry or room for batteries into other portable devices like portable GPS units without forfeiting storage capacity.

A compact solid-state storage alternative to the 2.5” SSD.

The SD card technology is optimised as a random storage medium in a similar way to the hard disk or the classic floppy disks. In this case, the microSDHC card can be used as a compact solid-state storage medium which is occasionally removed.

For example, a 32Gb microSDHC hidden behind a service panel could be useful as a system drive (boot, operating system, applications, hibernate file and registry) in a laptop or notebook computer with a regular 2.5” hard disk being used for user data. For printers and all-in-one devices, this card would work as a larger temporary storage for applications like keeping the print or fax queue for reliable and convenient printer operation.

Conclusion

The main reason I am blogging on the 32GB MicroSDHC card is because it is an example of the direction that solid-state secondary storage is taking, whether in a removeable or fixed form
