4. PRINTING SECTION

Image data is printed on recording paper that arrives from the pickup sec-

tion. This section describes the printing sections of an LBP and a BJ

printer.

4.1

LBP (LASER Beam Printer)

As its name implies, an LBP prints images using a LASER beam. This

printer is quiet during printing as it does not generate the kind of impact

noise that is generated on a typewriter. Another feature of this printer is its

fast printing speed as it is a type of page printer and prints images in single

pages at a time.

4.2

Printing by LASER

Image data is divided into 

 (dot) units. Each of these pixels is made to

correspond to a LASER spot, and images are printed by turning LASER

spots ON and OFF.

Fig. 4-26   LASER Printing 1

As the LASER beam itself only advances straight, the LASER beam is

reflected on a rotating scanning mirror to scan in the horizontal scanning

direction. Scanning for one line’s worth of the image is performed on one

of the planes of the scanning mirror. To draw the next line, the location to

be scanned itself advances by one line.
