Problem Possible Cause and Solution 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 noncompliant 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. 7 SOLVING PROBLEMS 7.33
