When State Saving is Off, fonts and printer macros downloaded from
your software application are cleared from memory when:
• The printer switches from one page description language (PDL) to
another (such as from PostScript to PCL).
• A memory reconfiguration takes place (such as for a new Page
Protection or Resolution setting).
When State Saving is On, the printer reserves memory to retain the
downloaded fonts and macros. Thus, the fonts and macros do not have to
be downloaded to memory again when switching PDLs or reconfiguring
memory.
You may set State Saving separately for the PCL and the PostScript
environments.
The Windows PostScript driver for the 4520 allows the user to either
download the PostScript header with every job or download it only once. If
the printer is used in a network or other shared environment, where both
PCL and PostScript jobs are printed, the header will be deleted when the
printer switches from PostScript to PCL. Banner sheets printed from Novell
networks cause the printer to switch between PostScript and PCL. If banner
sheets are printed, insure that the Language Sensing option is ON and
the default language is PCL. To avoid the loss of the PostScript header,
select "Download Each Job" in the PostScript driver. The "Already
Downloaded" option may be selected if at least 20 MB of memory is
installed in the printer and the State Saving option is set to ON in the
PostScript printer menu. The user is required to download the header at
least once for each power on cycle. If several different PostScript
applications are used, the "Download Each Job" option will guarantee that
the correct header is always available. See Figure 3.24 (page 3-72) for
memory requirements.
