Decide what types of documents you will be printing (text, graphics, odd paper sizes, etc.).
Make a list of specific features you need, such as the ability to handle large files, the ability to print on various media (labels, envelopes) with-out jamming, a size to fit a particular desk space, two or more paper trays, and compatibility with specific software.
Compare the print quality of different printers. Compare the resolution, or dpi (dots per inch). Use a magnifying glass if print quality is critical.
Compare speed specifications. Although you probably won't get the rated speed at home, the ratings are useful for comparing printers.
Learn how much RAM the printers have, and whether it's expandable.
Realize that the printer's paper path needs to be no sharper than 90 degrees to consistently handle envelopes, labels, transparencies or card stock. If you plan to use special media often, avoid printers with 180- degree U-turn paper paths.
Compare prices of consumable items such as toner cartridges and replacement drums.
Compare warranties and service contracts.
- Look for at least 600-by-600 dpi (dots per inch) resolution.
- If you want to print PostScript fonts or PostScript graphics, you'll need a PostScript printer. Many, but not all, laser printers can handle PostScript; most ink-jet printers can't.
- Printer RAM will affect the printer's speed and ability to handle large files. If the printer includes many built-in fonts, that may also
- improve speed.
- You may need to purchase the printer cable separately.
- Be wary of terms such as "laser class printer." These inexpensive printers use toner cartridges, but use LEDs instead of lasers, and produce an inferior text quality.
