Resource Saving (HP LaserJet 4 Plus and 5 only)

Resource Saving gives the printer the ability to save certain entities such as permanent soft fonts, macros, symbol sets and user-defined graphics patterns when the printer changes personalities, resolutions or page protect modes. For example, if a user switches the LaserJet 4 printer from PCL mode to PostScript mode, all PCL soft fonts macros are lost. The HP LaserJet 4 Plus/4M Plus printer would not clear these entities from memory. When the user switches back to PCL from PostScript all of the PCL entities would still be resident in the HP LaserJet 4 Plus/4M Plus printer. Resource Saving can only be accessed when the printer has the PostScript language installed and a minimum memory configuration of 7 MB. If the printer has a duplexer option, the minimum amount of memory necessary to access Resource Saving is 13 MB.

The Resource Saving configuration is located in the Memory Configuration Menu. Resource Saving can be set for three modes, AUTO (default), ON, and OFF. Auto configuration sets the Resource Saving for PCL and Postscript to a minimum value (400 KBytes) for each personality. Setting Resource Saving to ON allows the user to determine how much printer memory will be used for Resource Saving for the PCL personality and the Postscript personality. The memory can be allocated in 100 KBytes increments. For example, if the user sets the Resource Saving memory size to 200 KBytes, a total of 400 KBytes of memory will be assigned to Resource Saving. 200 KBytes of memory will be used for Postscript Resource Saving and 200 KBytes of memory will be used for PCL Resource Saving. Turning Resource Saving OFF disables the Resource Saving function and no memory is allocated to Resource Saving.
