Menu Administration/Emulations/PCL 5E/Retain Temporary
Choices Off, On, On Compatibility
Off — Resets PCL to its default state at the end of
each PCL print job, executes an implicit <ESC>E
at the start and end of the job, and deletes any
temporary fonts, macros, and patterns.
On — Resets PCL to its default state at the end of
each PCL print job. Temporary fonts, macros, and
patterns from previous PCL jobs are retained in
memory after the print job has completed. You can
recall these downloaded fonts, macros, or patterns
from within your PCL file without having to
download them again.
On Compatibility — Retains the entire state of PCL as
well as the temporary macros, fonts, and patterns
from previous PCL jobs.
