On my PCL (or GDI)
printer, I sometimes get error messages
printing instead of my
document.
Unfortunately, some Unix applications may generate
non-compliant PostScript output that may not be
supported by Ghostscript, or even the printer itself in
PostScript mode. You can try to capture the output to
a file and view the results with Ghostscript (gv or
ghostview will allow you to do so interactively) and
see if you get error messages. However, since the
application is probably at fault, contact your software
vendor to inform them of the issue.
Some color images come out all black.
This is a known bug in Ghostscript (until GNU
Ghostscript version 7.05) when the base color space
of the document is indexed color space and it is
converted through CIE color space. Because
Postscript uses CIE color space for Color Matching
System, you should upgrade Ghostscript on your
system to at least GNU Ghostscript version 7.06 or
later. You can find recent Ghostscript versions at
www.ghostscript.com.
