Difference Between Inkjet Printer and Dot Matrix Printer

Inkjet Printer vs Dot Matrix Printer

Summary: Difference Between Inkjet Printer and Dot Matrix Printer is that ink-jet printer is a type of non-impact printer that forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper. While dot-matrix printer produces printed images when tiny wire pins on a print head mechanism strike an inked ribbon. When the ribbon presses against the paper, it creates dots that form characters and graphics.

Difference Between Inkjet Printer and Dot Matrix Printer

Inkjet Printer

An ink-jet printer is a type of non-impact printer that forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper. Ink-jet printers have become a popular type of color printer for use in the home. Ink-jet printers produce text and graphics in both black-and-white and color on a variety of paper types. A reasonable quality ink-jet printer costs less than $100.

As with many other input and output devices, one factor that determines the quality of an ink-jet printer is its resolution. Printer resolution is measured by the number of dots per inch (dpi) a printer can print. Most ink-jet printers can print from 1200 to 4800 dpi. The speed of an ink-jet printer is measured by the number of pages per minute (ppm) it can print. Most ink-jet printers print from 12 to 36 ppm. Graphics and colors print at a slower rate.

The print head mechanism in an ink-jet printer contains ink-filled cartridges. Each cartridge has fifty to several hundred small ink holes, or nozzles. The ink propels through any combination of the nozzles to form a character or image on the paper. When the ink cartridge runs out of ink, you simply replace the cartridge. Most ink-jet printers use two or more ink cartridges: one containing black ink and the other(s) containing colors. Consider the number of ink cartridges a printer requires, along with the cost of the cartridges, when purchasing a printer. To reduce the expense of purchasing cartridges, some users opt to purchase refilled cartridges or have empty cartridges refilled by a third party vendor.

Dot Matrix Printer

A dot-matrix printer produces printed images when tiny wire pins on a print head mechanism strike an inked ribbon. When the ribbon presses against the paper, it creates dots that form characters and graphics. Dot-matrix printers typically use continuous form paper, in which thousands of sheets of paper are connected together end to end. The pages have holes along the sides to help feed the paper through the printer. The speed of most dot-matrix printers ranges from 375 to 1100 characters per second (cps), depending on the desired print quality.
