This object enables a printing mode wherein the printer
compresses selected scanlines of raster image data as they are
received and holds them in compressed form until they are to
be printed. This allows particular jobs to be processed with
less memory, but often reduced performance as well.
On some Printers, turning this feature Off is referred to as
'PerformanceEnhancement'.
When xcmInterpPageProtect is set to Off,
some complex jobs may not print successfully with minimum
memory. The ScanlineCompaction feature enables printing some
complex jobs without resorting to reserving additional memory
by turning on the PageProtect option or installing additional
memory.
