Glossary

inkjet printer A printing device that generates images by shooting dots of liquid ink against a printing surface. Resolutions vary between 300 and 1200 dpi (dots per inch). When selecting printers, the higher the dpi, the sharper the image.

Inkjet printers themselves are very inexpensive, however the cost printing is relatively high because of the cost of ink.

Inkjet printers are almost all capable of printing in color.

 

laser printer A printing device that generates images by fusing a black powder (toner) to a printing surface using a laser. Resolutions vary between 300 and 1200 dpi (dots per inch). When selecting printers, the higher the dpi, the sharper the image

Laser printers themselves are relatively expensive, however the cost of printing is relatively low because, ounce for ounce, toner will yield far more pages than ink.

 

impact printer A printing device that generates images by striking an ink-filled ribbon against a printing surface, much like a type writer. Resolutions are typically lower than those of inkjet and laser printers. Most use just black ink, but many also print in color. 

Impact printers are relatively inexpensive, and the cost of printing is also low because ink ribbons are inexpensive.

Because impact printers physically strike a page to print, they can be used to print on carbon copy paper.

 

ribbon shield A ribbon shield is a long, plastic device that presses paper against the printer's roller so that the printer ribbon does not rub-up against the paper and leave smears.

 

toner cartridge Toner is a dry ink that laser printers use to print images. Toner cartridges are simply cartridges containing toner that are snapped into laser printers. Toner covers a page more efficiently than liquid ink, and therefore does so less expensively than liquid ink.
