PostScript-Specific Variables
The following table lists the currently defined PostScript-specific
variables. These variables can be set using the LPARM :
POSTSCRIPT option.
Variable Description
Sample Value
Range
ADOBEMBT Normally, when PostScript formats a page in
memory for printing, it formats a full page
(full frame). This is the normal operation for
PostScript (Adobe MBT set to OFF). In order
for the printer to format full frame it must
have sufficient memory to store the full page.
If there is not sufficient memory the printer
will perform some compression on the page
to get it to fit in memory. Printed images on
these pages may result in the loss of some
detail from the original. This formatting
method requires considerable memory. With
ADOBEMBT ON (enabled), the printer
formats a PostScript page in strips. This
method does not require as much memory
and will not result in loss of detail in images,
however it is a little slower and can require
up to 20% more formatting time. With
ADOBEMBT set to AUTO, the printer will
select either full frame, depending on the
selected page size and the amount of
memory available, or ADOBE MBT. For
example, if letter is the page size and the
printer has 7 Mb of memory available, the
printer will print full frame (disable MBT); if
less than 7 Mb is available, the printer will
enable MBT and process the page in strips.
OFF, ON, AUTO
JAMRECOVERY Enables or disables the printing of jammed
pages following a paper jam. The OFF
setting boosts printer performance, but lost
pages are not automatically printed after
clearing the jam.
OFF, ON
PRTPSERRS This variable enables or disables the printing
of a PostScript error page.
OFF, ON
