Description: Returns or changes PDL resource saving. Resource saving stores a PDL's permanent soft resources, like fonts, even when another PDL is active. Resource saving is also called environment saving. When eOff, resource saving is disabled. When ON, resource saving is enabled and memory is set aside for each PDL based on that PDL's resource saving memory size object, to store that PDL's permanent soft resources. When eAuto, resource saving is enabled and memory space for each installed PDL is determined automatically. The device POS should document what values are legal when only one PDL is installed. Additional information: When PCL (including PCL/XL) is the only PDL installed in The LJ Series 4000, eOn is not a legal value. Attempting to set this object to eOn with a PCL-only printer will result in a status of being returned. When Postscript is installed and less than 8 Megabytes of RAM are present, resource saving is not available. The only valid value for this object is eOff. Attempting to set this object to eOn or eAuto will cause to be returned. When Postscript and 8 Megabytes or more of RAM are installed, all values are valid, provided I/O Buffering, Mopying, or Ram Disk have not consumed the needed memory. This object is only supported if Postscript is resident in the printer.
