Samsung CLX-3185 Service Manual page 136

Continue..
I have CUPS and some
options (such as N-up) seem to be always
enabled even though I don't
choose them in LLPR.
I configured a printer to
print to a file, but I get "Permission
denied" errors.
On my PCL (or GDI)
printer, I sometimes get error messages
printing instead of my
document.
Some color images come out all black.
Service Manual
Alignment & Troubleshooting
There may be some local options defined in your ~/ .
lpoptions file, which are manipulated by the lpoptions
command. These options are always used if not
overridden by LLPR settings. To get rid of all options
for a printer, run the following command, replacing
"printer" with the name of the queue:
lpoptions -x printer
Most printing systems will not run as the super-user
but as a special user (usually "lp"). Therefore, make
sure that the file you have chosen to print to is
accessible to the user owning the spooler daemon.
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.
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.
