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.
