b. Protocol Controller PCB

In terms of PDL units, the Printer Board that may be installed to the machine may be a PS-PCL Board,

PCL5e Board, or PS (kanji) Board. Of them, the three boards may be used in common with the Multi
Device Controller, requiring conversion of printing commands (printer commands) and operation
sequences to suit the operating environment of the GP215/GP200.

The Protocol Controller PCB converts printer commands from a personal computer to control the print-

er system of the GP215/GP200 to support GP215/GP200-specific multiple cassette functions not found in
a configuration consisting of a Multi Device Controller and a GP55/GP30F.
