Description
Automatic recognition of the page description
language (PDL) used in an incoming print job.
When On, if the serial port receives print jobs of
different PDLs—such as a PostScript print job followed
by a PCL print job—it can automatically sense which
PDL the print job is using. It does this by sampling the
incoming data stream, then switching to the
perceived language for that job or to the System
Language setting if it fails to sense the language.
When On, if State Saving (page 3-28) in the PCL
Menu or State Saving (page 3-37) in the PostScript
Menu is also On, the permanently downloaded fonts
and macros are saved in memory, eliminating the time
to download them again when switching between
PDLs occurs.
