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.
|
| 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.
