S OLVING P ROBLEMS 7.33

I have CUPS and some
options (such as N-up)
seem to be always enabled
even though I don’t choose
them in LLPR. 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
I configured a printer to
print to a file, but I get
“Permission denied” errors. 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.
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 at fault probably, contact your
software vendor to inform them of the issue.
Some color images come
out all black. This is a known bug of 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 at least GNU Ghostscript version 7.06 or later. You can
find the recent Ghostscript at www.ghostscript.com.
