XEROX DOCUPRINT NPS GUIDE TO USING PAGE DESCRIPTION LANGUAGES
DocuPrint NPS implements the PostScript Level 2 operators; it
conforms to the PostScript Language as defined in the PostScript
Language reference manuals.
DocuPrint does not support the following device-specific operators:
banddevice, framedevice, and renderbands (device setup and
output operators). These operators are device-specific.
•
In PostScript Level 2, the LZWEncode, CCITTFaxEncode, and
DCTEncode filter names are not supported with the filter
operator.
Note: The DCTDecode filter does not work correctly for all full
color images.
•
Unlike the Adobe implementation of PS Level 2, the
setfileposition operator is permitted on %stdin when the
standard input comes from a file.
•
The charpath operator is not supported with the PostScript
Level 1 interpreter when used on type 3 fonts, However, this
operator is supported with PostScript Level 2.
Due to support of mixed paper sizes, PostScript files that use the
clippath pathbbox operators to determine the imageable area of the
page will not image shift correctly. Image shifting will not occur by
using the AdjustX and AdjustY system options nor the image shift
document attributes: HorizontalImageShift,
HorizontalImageShiftforBack, VerticalImageShift,
VerticalImageShiftforBack, and the ExceptionPage image shift.
For releases prior to 7.x, simulated mixed plex is supported using the
standard PostScript Level 2 /Duplex pagedevice key. The /Duplex
key is supported only with the PostScript Level 2 interpreter when the
plex attribute value is "duplex." The /Tumble key is not supported.
The /Duplex key is not supported when used in a job with the
MultiSet-specific pagedevice keys: /EndOfSet, /EndOfRun, and
/Staple, which are also capable of simulating mixed plex.
For more information on mixed plex jobs, see the chapter "Mixed plex
applications" in the Guide to Managing Print Jobs.
