Laser Printers

The most common type of printers’ used by mid to large size businesses and some and home users is laser printers. Because laser printers represent a large percentage of calls to PC technicians, CompTIA has made them a significant focus on their A+ Core Technologies test.

The entire printing process revolves around a special device contained within the print cartridge called a photosensitive drum. The process in which a page is printed from a laser printer involves six stages:

  1. Cleaning

  2. Conditioning

  3. Writing

  4. Developing

  5. Transferring

  6. Fusing

This process is specifically the HP printing process. It is the only laser printing process covered on the A+ Core Technologies exam.
