Laser Printer
Operation
A laser printer is a type of printer that can print text or graphics in both black and color with high quality.
Laser printers work by creating an electrostatic image of a full page on a photosensitive drum with a laser beam. When applied to the drum color Ultrafine powder called toner, it binds only to the sensitized areas corresponding to the letters or images on the page. The drum rotates and is pressed against a sheet of paper, transferring the toner to the page and creating the image. This technology is similar to that used copiers, although there are differences in the details of the transfer the image and the internal temperature of the units.
Thermal Printers
Operation
thermal printers work inkjet ink cartridge overheating to about 400 ยบ F. This produces vapor bubbles inside the cartridge, which rise to the top of the chamber. Steam pressure forces the ink out of the cartridge through the nozzles into tiny droplets that form the dots on the page. The vacuum created by the ejected ink pushes ink into the nozzle, generating a steady flow of drops required.
Piezoelectric Printer
Operation
piezoelectric print heads can use ink dries faster and pigments could be damaged by temperatures of a head Thermal also has a piezo head printer is integrated. Just need to replace an ink cartridge. (Thermal printers include nozzles for each ink cartridge, which increases the cost of the cartridge and the cost for both pages.) The disadvantage that if a piezo head is damaged or gets stuck, it is necessary to repair the printer
