Description: Returns the maximum amount of additional memory, in bytes, that can be dedicated to buffering print job data. Additional information: Memory for I/O Buffering is allocated in increments of 102400 bytes. Therefore, for each 1M (1048576 bytes) of memory added to the printer, 1024000 bytes are made available to resource saving (and I/O buffering) and 24576 bytes are retained until an additional 102400 byte block can be made available. The value reported by this object is always rounded down to the nearest multiple of 102400. The values listed below assume that IO-BUFFERING=eOff; if IO-BUFFERING=eOn, the value returned by this object will be reduced by the amount of memory used by the IO-BUFFERING object. For a PCL-only printer, the value of this object is 102400 if 4M memory is installed or all the memory over 4M. If PostScript is installed without a duplex unit, the value of this object is as follows: 0K if <12M memory is installed. 102400 if 12M memory is installed. All over 12M memory installed. If PostScript is installed with a duplex unit, the value of this object is as follows: 0K if <23M memory is installed. 102400 if 23M memory is installed. All over 23M memory installed.
