Other considerations: The printer driver
The printer driver is important when choosing a printer for two reasons: it acts as the interface software between your PC and the printer, and it is the access point that allows you to control the media stock and print quality from your desktop.
If possible, get a demonstration of the driver and other software in action before you buy. How much control over the quality of the printout does it give you? How easy is it to switch the default paper size from Letter to A4 (a surprising bugbear in a number of printer drivers)? How well does it allow you to manage pending jobs?
Perhaps most importantly, what kind of feedback does it give you about the printer status - how much toner is left, what is the printer currently doing and why is the printer not working the way it should?
This illustrates one of the key points when buying a laser printer - especially one for which you are handing over a considerable amount of money. Get a demonstration, if you can. It could save you a lot of pain in the long run.

Is it environmentally friendly?
There are a lot of tricks that printer manufacturers can pull to save the environment - and the money and health of the buyer. Some things to look for include power consumption, power saving modes (such as whether the printer only warms up when used), ozone filters (to prevent excessive ozone emissions from the printer), cartridge refilling and cartridge disposability.
Kyocera deserves special praise in terms of the environmental-friendliness of its printers. Even the toner cartridges are built from plastics that release no toxic gases when incinerated.
| GLOSSARY | |
| CMY and K. Cyan, Magenta, Yellow and blacK | The four colours used in most printers. In combination, they can replicate just about any colour in the spectrum. |
| Consumable | A part of the printer (such as toner) that needs periodic 'refilling'. |
| dpi (dots per inch) | A measure of the resolution of the printer. Refers to how fine the dots are, and consequently how noticeable they are (the higher the dpi, the better). |
| Duplex | The ability to print on both sides of a sheet of paper without manual intervention. |
| LED printer | A more recent development than lasers, LED printers don't technically use lasers, but they are considered in the same category as laser printers (sometimes they are, in fact, marketed as 'laser printers'). LED printers use an array of light-emitting diodes instead of a laser to write to an OPC drum. They have comparable speed and print quality to lasers, and can be considerably cheaper and smaller than laser printers. They work best for long, continuous print runs rather than numerous short runs, as the drum will wear out quickly if it constantly has to stop and restart. There are also LCD (liquid crystal display) printers that work on a similar principle. |
| Memory | Used to store fonts and pending documents in a printer. |
| OPC (organic photoconductive) drum | The heart of the laser printer. A drum is charged with static electricity. The laser within the printer strikes the drum, reversing the polarity of the static charge and magnetising certain parts of the drum (the parts where the toner is meant to stick). The drum is then rolled through the toner, which 'sticks' to the now-magnetic parts of the drum. Finally, the drum is rolled over the paper and the toner is heat-fused into the paper. In many printers, the OPC drum has to be replaced periodically. |
| PDL (page description languages) | The page format that the printer understands and can translate into printed documents. Unless you're in publishing, which of the three major formats the printer uses (Postscript, PCL or GDI) makes little practical difference, since the printer's software driver will handle the process of converting the stuff you have on screen to something the printer can understand and turn into printed pages. |
| ppm (pages per minute) | The rate at which the printer can output finished pages. |
| Print server | Holds a queue of documents for the printer. |
| Resolution Enhancement technology (REt) | Printer manufacturers have laid claim to a number of tricks, such as special curve algorithms and varying dot sizes, that improve the image quality of the printout. While they may claim this 'doubles' the effective resolution, it doesn't. A 1200dpi printer is still better than a 600dpi printer with REt. |
| RISC processor | A type of processor frequently used in laser printers. |
| Toner | The 'ink' that a laser printer uses. Toner is fused onto the paper's surface, rather than absorbed into it (as is the case with inkjet printers), and so does not bleed or smudge as ink does. |
