Buyer’s Guide–Buying a printer for your small business

Introduction

You might be at that position where the computer printer at your small business is “on its last legs” or becoming impossible to run economically. On the other hand, you may find you are working your existing printer harder and need to consider a machine that is suited to your current workload.

Similarly, as the end of the financial year approaches, you will face advertising from computer resellers and retailers; and office-supply stores for technology like printers at very enticing prices, usually to allow businesses to buy capital equipment that can be quickly offset against their income for tax purposes. This can become more intense whenever the government announces significant tax breaks for business owners when they purchase capital equipment.

At this point, you could easily make a mistake concerning the purchase of a printer and end up buying the wrong machine for your needs. I have prepared this buyers’ guide so you can be sure you are getting the right printer to suit your business’s needs and be able to use a machine that gives you more “bang for the buck”.

Printer classes

Laser printers

A laser printer uses a xerographic dry-printing mechanism to print the image to the paper, in a similar way to how the classic photocopier worked. But they use a laser or, in cheaper printers, an LED to illuminate the photostatic drum with the computer-generated image to be printed.

Colour laser printers use four of these mechanisms to imprint the four colours and some cheaper versions may use only one drum and four toners to print the same page; which will take longer to come out.

This class of printer is typically known for printing many copies of “press-quality” documents and has started the “desktop-publishing” revolution.

It is worth knowing that some laser printers will use a cartridge which has an integrated drum as well as the toner supply while others like most of the Brother range will use a separately-replaceable drum unit. With the latter model, you may have to factor in the cost of the drum unit which will occur later on in the machine’s life; usually after 17000-25000 pages.

Business Inkjet printers

This class of inkjet printer is pitched primarily at business users and uses high-capacity cartridges and is optimised for a high duty cycle. They will also have business-target functionality like advanced fax functionality and the ability to work with advanced networks.

Consumer Inkjet printers

Typically this class of network printer will be optimised for photographic printing and have inks that reproduce photos well. But on the other hand, they will be optimised for a low duty cycle with low-capacity ink cartridges. If they have fax functionality, this functionality will be very basic and as far as network connectivity is concerned, these printers will be suited to a basic small network.

Buying dilemmas that a business owner can face

As a business owner, you may face some buying dilemmas when you choose certain printers. This is especially as manufacturers design printers, especially multifunction printers, that effectively have similar capabilities to others of a different class. Here, the prices for the machines are similar and they may have similar print speeds or functionalities. But there may be certain key differences like the cost to run the machine or the machine’s prowess at particular print jobs.

The two main examples of this are: a high-end fax-equipped consumer inkjet multifunction like the HP Photosmart Premium Fax C410a ( an ePrint-enabled successor to the HP Photosmart Premium Fax C309a full-duplex inkjet printer) and a network-capable business inkjet multifunction like the HP OfficeJet 6500A Series; or a high-end business inkjet multifunction like the HP OfficeJet Pro 8500 Series and en entry-level colour laser multifunction like the HP Colour LaserJet Pro CM1415fnw.

High-end consumer inkjet vs a business inkjet

A high-end consumer inkjet printer will be optimised for photo printing whereas a low-end networkable business inkjet will be primarily targeted at printing large runs of documents. This will affect ink-cartridge capacity, machine durability, functionality and printer throughput in many ways.

The former printer will typically have five or more inks and these inks will typically be in lower-capacity cartridges which need replacing more often than the four inks used in a low-end business inkjet printer. I would still suggest that businesses prefer the models with separately-replaceable ink cartridges because each ink can be replaced as needed.

As well, these consumer-level printers will typically have functions that make it easier to print pictures directly from a digital camera whether it’ is “tethered” by a USB cable or one takes the “film” (memory card) out of the camera. Some of these printers may offer the ability to print from a mobile phone via Bluetooth whether through integrated circuitry or an optional Bluetooth module.

It may be worth knowing that some business-level inkjets are acquiring this kind of functionality but most of these printers won’t turn out the high-quality prints from digital cameras. Here, this functionality may be useful for applications where print quality doesn’t matter like hardcopy proofs that are used for “shortlisting” pictures for a project.

I would consider the premium consumer-level inkjet printer as a business printer if you rely on it for turning out high-quality digital prints whether from your PC or your digital camera and don’t do much printing on it. If you want the best of both worlds, you could get by with a dedicated photo-optimised printer for photographic jobs and a business-grade multifunction printer for regular business printouts.

High-end business inkjet vs an entry-level colour laser

An example of this situation is HP’s OfficeJet Pro 8500a inkjet and the HP Colour LaserJet Pro CM1415fnw.

These printers have a similar throughput to each other when printing pages and also turn out a similar copy quality for the documents that are printed. It doesn’t matter whether the documents are ordinary text documents or documents filled with graphics. There may be some glaring functionality differences like the support for duplex operation or memory type. In this example, the OfficeJet Pro 8500a had “full duplex” functionality where it could print on both sides of a sheet of paper and scan both sides of a printed document whereas the LaserJet Pro CM1415fnw could only print or scan one side of a page. Conversely, the LaserJet Pro used flash memory for its fax-related features like no-paper receive, “fax vault” or send-later while the OfficeJet Pro used regular RAM memory for the same functions.

The cost-per-page for an entry-level colour laser printer is slightly cheaper than a high-end business inkjet that is fed the high-capacity cartridges although manufacturers like HP are  implementing ink cartridges in these printers that have a similar or better cost-per-page to the laser printers.  On the other hand, the inkjet is more flexible with print media than the laser because it doesn’t use any heat to bond the marking material to the paper. This can make it useful for printing short-run documents to glossy material or printing out labels and transparencies.

Dedicated printer vs multifunction printers

An increasing number of printers on the market, like most of the printers I have reviewed on this site, are of the “multifunction” type with a built-in scanner mechanism. Here, these printers will be able to scan to the computer or work as convenience light-duty photocopiers. Most of the business-focused multifunction printers are able to work as fax machines and these units typically are equipped with an automatic document feeder.

Compare this with the dedicated printers which just print from a computer. This class of printer is typically represented by laser printers or some photo-grade inkjet printers pitched at the graphic arts users.

A multifunction printer can work well as an all-round “workhorse” printer for most office applications whereas a dedicated printer can serve “infill” requirements that the multifunction cannot achieve. For example, you could use a colour inkjet multifunction printer as the main office printer in a doctor’s office while you have a monochrome laser printer turning out health-insurance forms and accounts that are part of the workflow. Similarly, you could use an A3 colour inkjet printer for turning out plans, signs and similar documents while you use a regular A4 multifunction for regular printing needs.

Features worthy of note

Auto-duplex printing

A feature that is becoming common amongst a lot of printers is auto-duplex printing. Here, the printer is able to automatically “flip” the page to print on the reverse side of the paper. This has become popular as a paper-saving measure but some of us may find it of value as a desktop-publishing benefit.

This is demonstrably so with laser printers like the Brother HL4150CDN colour laser that I recently reviewed. Here, the printer can print “to the edge” yet work on both sides of the page. As well, laser printers don’t have to “dwell” for up to 15 seconds to allow the ink to dry, thus it doesn’t have significant impact on print speed. Infact the previously-mentioned Brother printer could work both sides of two pages at once and with this, there is effectively no throughput penalty if you intend to do duplex or booklet printing.

Some inkjet printers, namely HP printers, may require a non-printed margin at the top and bottom of the page for auto-duplex printing. This is perceived to permit reliable paper handling but can be a problem if you intend to print landscape documents or “work to the edge” in your documents. It is also worth noting that some printers such as cheaper high-throughput colour lasers may only be able to use this function for the common document paper sizes like A4 or Letter.

At the moment, it is worth noting that not many of these colour laser printers that have auto-duplex printing can print on both sides of small-page “flyer-size” documents like A5, DL or postcard. This is usually because the auto-duplex mechanisms are not able to reliably push the small sheets of paper through the colour laser printing mechanism in order to print on both sides of the flyer.

It may be worth knowing that some high-end A4 multifunction printers will be likely to have “full duplex” functionality. This means that they will have auto-duplex printing as well as an automatic document feeder that can scan both sides of a page. This typically leads to functions like automatic “both-sides” copying and faxing.

Use as the business fax machine

Firstly, most of the multifunction printers that appeal to the business user will have an integrated fax functionality. This can be of use if that old fax machine has nearly “had it” or is becoming costly to run due to its use of the thermal-transfer tape.

Infact, the purchase of a low-end plain-paper fax that uses this kind of printing is really a false economy because these fax machines will work through the thermal-transfer tape even if a page is partially written on. Instead, a fax-equipped multifunction printer uses the ink or toner when and where it needs to mark the document.

As well, it will save on bench space because you don’t have to have a separate machine to receive your faxes on. This is an important requirement for small offices and shops where this space can be at a premium.

It is also worth knowing that the inkjet and colour-laser multifunction printers that have the fax functionality are capable of receiving and transmitting faxes in colour to businesses equipped with similarly-capable equipment. Here, if you select “Colour Fax” on these machines, they will transmit the document according to “best-case” rules where if the receiving machine isn’t colour-capable, the transmission will succeed with the document being in monochrome. Other examples of these printers offering increased value for money as a small-business fax machine include the business class printers offering a “fax-vault” function where you can set the unit to hold received documents in memory and print them when required; or “print-to-fax” functions or “fax-to-computer” functions so you can fax a document from your computer or capture a faxed document to your computer without reprinting it.

Of course, these machines will have the expected fax functionality and can work with a dedicated fax line or a shared phone line, including support for “distinctive ring” dedicated-fax-number setups like Telstra’s Faxstream Duet.

What to be careful of

The two-cartridge colour inkjet printer

A lot of inexpensive consumer and small-business inkjet printers still use two cartridges for their printing setup. One of these cartridges is the black cartridge while the other is a “tri-colour” ink cartridge that houses the cyan, magenta and yellow inks in one plastic body.

The main problem with this design is that if one colour runs out in the colour cartridge, you have to replace the whole cartridge even if there is plenty of ink remaining for the other colours. It can become more exacerbating if you print material using your business’s trad dress which will be dominant in particular colours.

This may be OK for an occasionally-used printer but should be avoided if you use your printer frequently. Instead, look for a midrange printer that uses four or more ink cartridges with each colour in its own cartridge.

Wi-Fi-only network connectivity

Another feature common with inexpensive network multifunction printers is to provide Wi-Fi as the only network connection method. This is more so with the printers that are positioned at the consumer end of the market.

There are a few limitations with this setup. One is that you have to run a Wi-Fi network to obtain the benefits of network connectivity and this can be fraught with problems because of Wi-Fi being a radio based method. For example, walls made out of double-brick, cinder-block or reinforced concrete can play havoc with a Wi-Fi link; as can metal-reflective insulation. This limits the ability to connect the printer to your business network using alternative network technologies like Ethernet or HomePlug powerline networking.

As well, a lot of these printers require the user to configure them for the wireless network by connecting them to a host computer and running manufacturer-supplied software before they will work with that network. The exception to this rule for most of these printers is Wi-Fi network segments that use WPS “push-to-connect” setup, where you may push a button on the printer or select a menu option to start the configuration process. This is although the HP ePrint-enabled Wi-Fi-only consumer printers like the Photosmart Wireless-E B110a economy printer and the HP Envy 100 (D410) slimline printer do support configuration for non-WPS wireless networks from the control panel.

Recommendations for most businesses

General-office work

I would recommend a midrange network-connected business inkjet multifunction printer with four ink cartridges and auto-duplex printing for a “general-use” workhorse printer. It may be OK to use a high-end consumer printer or low-end business inkjet for low-traffic applications like a secondary printer.

A photo-optimised consumer printer like a Canon PiXMA or HP Photosmart may be good as a secondary printer for applications where you value high-quality photo prints with the full saturation. Some manufacturers may offer a dedicated photo-optimised printer but typically these can be very expensive and are pitched at the graphic-arts industries.

A dedicated monochrome laser printers can be useful for printing out forms or documents as what would be required of medical, legal or similar professions. Here, it would be wise to look for auto-duplex-equipped units if you turn out many multipage documents like most legal documents. As well, I would recommend that these machines are network-connected if you have or intend to have two or more computer workstations that will turn out the documents.

If you don’t care about colour printing but turn out many documents, you could get by with a monochrome laser multifunction printer like the recently-released Brother units or the HP LaserJet M1212nf that I had previously reviewed. Then if you want to do colour printing at a later date, you could add on a dedicated colour printer like the HP OfficeJet 6000 inkjet; HP OfficeJet 7000 A3 inkjet or Brother HL-4150CDN laser “desktop-publishing workhorse”.

Promoting your business yourself

You may want to use a colour laser printer as a promotion tool for your business. I have infact written up an article about why it is worth considering these printers as a buying option. Here, it would be a good idea to stick to high-throughput colour laser printers like the Brother HL-4150CDN especially if you do a lot of your own short-run publishing, including “infill” print runs.

You may want to take advantage of the larger A3 page size as a paper size for signage and similar material. It may even come in handy within the office for turning out large spreadsheets or business charts that can have more detail. Here, you may look at a single-tray A3 multifunction like the HP OfficeJet 7500 for occasional A3 use or a dual-tray A3 multifunction like the Brother MFC-6490CW or dedicated A3 printer like the HP OfficeJet 7000 if you do turn out a lot of A3 material.

Conclusion

In simple terms, I would suggest that you check how much the printer will cost to run; such as the price of replacement ink or toner cartridges; the availability of high-capacity cartridges and the kid of cartridges used and other cost-saving practices like auto-duplex

Then make sure that your printer can suit your current needs as well as allowing for future needs.Here, you can then own and run the right printer that will serve your business’s needs for many years without being a drain on your business’s cashflow.

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.
