NON IMPACT PRINTERS
Non impact printers are most widely used printers. These are incorporated with high speed and are quieter than impact printers as these have fewer moving parts. Non impact printers can produce both graphic and text. These printers print without striking the paper i.e. no physical contact with the paper. Most common example of non impact printers is Inkjet printers and Laser printers.
Inkjet printers are most famous among home and small scale offices due to reasonable cost and good quality of printing. A typical Inkjet printer can print with a resolution of more than 300 dpi. Moreover, good quality ink jet can also print 600 dpi. However, ink used in these printers is extremely expensive, and if the printout gets wet, it has the tendency to smear. Moreover, cheap ink can not be used for these printers. Therefore, one has to be very careful while refilling the ink. Laser printers are the fastest printers available in the market. The speed ranges from about 4 to 20 pages of text per minute. Therefore, a typical rate of 6 ppm is equivalent to about 40 characters per second. These produce sharp and crisp images of both graphic and text printing in many fonts (type style and sizes).
