Context Saving

allows the printer to remember information about the current data
stream when it switches back and forth from one job type (PostScript or PCL5e) to
another. (Network Printer 17 always does context saving for IPDS.) For PCL5e,
this includes information about downloaded permanent fonts, macros, and
user-defined patterns. For PostScript, this includes all of the information found in
the PostScript VM allocation.
The Memory Configuration (MEMCONFIG) Menu provides two menu items, PCL
SAVE and PS SAVE, which allow you to set context saving on or off for each data
stream. These menu items are displayed only if there is enough memory in the
printer to permit context saving. The PS SAVE menu item is displayed only if the
PostScript SIMM is installed.
