Detailed explanation-1: -Impact printers are the type of printers in which a key strikes the paper to make a letter. The examples of Impact printers are Daisy wheel and Dot matrix printers. While non-impact printers do not operate by striking a head against a ribbon. Inkjet printers and laser printers are the non-impact printers.
Detailed explanation-2: -A dot matrix printer is an impact printer that prints using a fixed number of pins or wires. Typically the pins or wires are arranged in one or several vertical columns. The pins strike an ink-coated ribbon and force contact between the ribbon and the paper, so that each pin makes a small dot on the paper.
Detailed explanation-3: -Daisy wheel printers from Diablo and Qume were the dominant high-end output technology for computer and office automation applications by 1980, though high speed non-impact techniques were already entering the market (e.g. IBM 6640 inkjet, Xerox 2700 and IBM 6670 laser).
Detailed explanation-4: -The types of line printers are drum printers, band-printers, and chain printers. Other non-impact technologies have also been used, as thermal line printers were popular in the 1970s and 1980s, and some inkjet and laser printers produce output a line or a page at a time.
