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 is the only PDL installed in LaserJet 5Si, all resource saving memory is dedicated to PCL so eOff is the only valid value. Attempting to set this object to eAuto or eOn with a PCL-only printer will result in a status of being returned. When PostScript is installed and there is less than 13M of memory installed, 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 a duplex unit are installed and there is less than 24M of memory installed, 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 13M (24M with duplex unit) or more are installed, all values are valid, provided I/O Buffering has not consumed the needed memory.
