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: This object is supported only if PostScript is installed. When PCL (including PCL/XL) is the only PDL installed in Laserjet 1220, 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 12M RAM is 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 a status of being returned. When PostScript is installed and 12M RAM or more are present, all values are valid
