D Printer Memory Keeping Downloaded Resources in Memory When only the PCL personality is installed, the printer uses all available memory to maintain downloaded resources. When two or more personalities are installed, the printer reserves a portion of memory for each personality's resources. The printer deletes downloaded resources from its memory when you change personalities or resolutions. For printers with more than one personality, Resource Saving enables the printer to keep downloaded resources in memory under most conditions. PCL-only printers do not require Resource Saving because available memory is automatically allocated to keep downloaded resources in memory. Resource Saving in PCL and PostScript Printers When the PostScript option is installed, Resource Saving automatically becomes available if 8 MBytes (or 13 MBytes in duplex mode) of memory or more are available in the printer. By default, the printer automatically allocates resources to each printer personality, depending on the amount of memory each personality needs. Most users will not need to customize the printer's Resource Saving configuration, but you can change the amount of memory allocated to each printer personality through Resource Saving (see the procedure on the following page).
