Printers are categorized based on whether the image is formed by hitting an ink ribbon against the paper or not.Non-impact printers do not have physical contact.Non-impact printers are quieter and faster than impact printers.There is no physical contact between the printing mechanism and the paper.Laser printers have a cylindrical drum that rolls charged ink onto the paper, while inkjet printers spray tiny drops of ink on the page.

It is possible to produce fine-quality images quickly and quietly with a non-impact printer.The printer consumables are easy to recycle.

The laser printer creates images with dots.One of the most popular types of printers are laser printers, which give a resolution from 300dpi to 1200dpi.They are both fast and quiet.

Inkjet printers use small charged droplets of ink from four nozzles through holes in a matrix at high speed to create images with tiny dots.The matrix consists of a print cartridge filled with liquid ink and small nozzles.They are slower than laser printers.An advancement on inkjet technology is the bubble-jet printer, which uses a type of small heating element which pushes specially formulated ink through print heads with 128 miniature nozzles.

When the element reaches a critical temperature, the output characters are formed by a special heating element placed with special heat-sensitive waxy paper.The cost of thermal printers is higher than other non-impact printers, but they produce high quality prints.
