based on various functional requirements. Notes: 1.   The PAGEPROT menu item is available on the PCL Menu, the PostScript (PS) Menu, and the IPDS Menu.   It determines whether or not the printer uses
compression when it prints complex pages. Ÿ    PAGEPROT=AUTO—the printer uses compression when it runs into memory       constraints.   This can reduce print speed.
Ÿ    PAGEPROT=ON—the printer does not use compression and therefore requires more memory. 2.   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 12 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. Chapter 1.   About Your Printer 3
