Summary: Difference Between Line Printer and Laser Printer is that line printer is a high-speed impact printer that prints an entire line at a time. While laser printer is a high-speed, high-quality non-impact printer.

Difference Between Line Printer and Laser Printer

Line Printer

A line printer is a high-speed impact printer that prints an entire line at a time. The speed of a line printer is measured by the number of lines per minute (lpm) it can print. Some line printers print as many as 3,000 lpm.

Laser Printer

A laser printer is a high-speed, high-quality non-impact printer. Laser printers for personal computers ordinarily use individual sheets of paper stored in one or more removable trays that slide in the printer case. Laser printers print text and graphics in high-quality resolutions, usually ranging from 1200 to 2400 dpi. While laser printers usually cost more than ink-jet printers, many models are available at affordable prices for the home user. Laser printers usually print at faster speeds than ink-jet printers. Printer manufacturers state that a laser printer for the home and small office user typically prints black-and-white text at speeds of 15 to 62 ppm. Color laser printers print 8 to 40 ppm. Laser printers for large business users print more than 150 ppm.

Depending on the quality, speed, and type of laser printer, the cost ranges from a few hundred to a few thousand dollars for the home and small office user, and several hundred thousand dollars for the large business user. Color laser printers are slightly higher priced than otherwise equivalent black-and-white laser printers. Operating in a manner similar to a copy machine, a laser printer creates images using a laser beam and powdered ink, called toner. Black-and-white laser printers use one toner cartridge. Color laser printers use multiple cartridges — one for black and one or more for colors. When the toner runs out, you replace the toner cartridge.
