RECORDING SECTION
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
correspond to a LASER spot, and images are printed by turning LASER
spots ON and OFF.
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.
