There are four kinds of printers in the world at the moment, and they are:

• Laser Printers
• Inkjet Printers
• Dot Matrix Printers
• Daisy Wheel Printers

Laser Printers have one large cartridge for black ink alone. Inkjet printers have four different cartridges: Cyan, Magenta, Yellow and Black, known simply as CMYK. It is CMYK instead of CMYB because the K is based on Key Black, instead of just black.

Different printers have different PPMs (Pages per minute). A laser printer can print 2 – 6 pages per minute, an inkjet printer can print about 8 – 200 pages per minute, when you think about it that is about 3 pages per second. Dot Matrix printers and daisy wheel printers take over a minute to print one page.

Dot Matrix and Daisy Wheel printers are also very noisy, while inkjet and laser printers, while printing more pages, are still more quiet. The quality of a printed piece is measured in dpm (dots per minute). The higher the dpm, the more resolution there will be.

Some common factors of reliability are:

• warranty
• scheduled servicing
• MTBF (Mean Time between failures).
