Processing Print Data

The machine processes print data using its PDL PCB.
The PDL PCB is not designed to directly generate image data out of data written in a
page description language. In preparation, it translates data written in a page description lan-
guage into data in a language used for internal processing; it then generates image data from
the resulting data. (The work is done by a function called "translator.")
