how are impact printer different from non impact printer
Answers
Answer:
Laser printer is non-impact printer
A type of printer that does not operate by striking a head against a ribbon. Examples of nonimpact printers include laser and ink-jet printers. The term nonimpactis important primarily in that it distinguishes quiet printers from noisy (impact) printers.
non-impact printer - Computer Definition. A printer that prints without banging a ribbon onto paper. Laser, LED, inkjet, solid ink, thermal wax transfer and dye sublimation printers are examples of non-impact printers. See printer.
Non-impact printers are generally much quieter than impact printers since they don't physically strike the page. For example, inkjet printers spray tiny drops of ink onto the page, while laser printers use a cylindrical drum that rolls electrically charged ink onto the paper. Both of these methods are non-impact and provide an efficient printing process that produces little sound. The low impact nature of inkjet and laser printers also means they are less likely to need maintenance or repairs than earlier impact printers.
