COLLATE
Specifies whether to collate the output, if collation
is supported by the device.
Comparisons
A limited number of
printers can
collate output,
which means to separate each copy of printed output when you print
multiple copies of output.
For PostScript printers,
if a device's PPD file has Collate defined as “True”,
the COLLATE option is supported.
For PCL printers that
support collation, use the GPROLOG= option to specify a Printer Job
Language (PJL) command to enable the collation. For information about
the appropriate PJL command, consult the Printer Commands section
of your printer's user manual.
