Hi, While trying to work out why Firefox refuses to print on one box, I've discovered that GUI applications won't print through "lpr" (the technique Firefox tries to use, and GEdit will let you pick), yet I can use lpr to print through the command line. e.g. lpr /home/tim/testpage.text This is the closest I can get to working out what's wrong, but still not resolve my problem (unable to print pages in Firefox). I've taken the brute force approach, renamed the /etc/cups directory and forcefully reinstalled CUPS, trying to see if that makes any difference. Doing a "rpm -Vv cups" shows no apparent problems with installed files. On three different FC4 boxes, I get different results for listing the lpr file, and they've all got the same version of CUPS installed (cups-1.1.23-15.4). Working boxes: -rwxr-xr-x 1 root root 17520 Jan 5 05:09 /usr/bin/lp.cups -rwxr-xr-x 1 root root 12808 Jan 27 02:21 /usr/bin/lpr.cups Problem box: -rwxr-xr-x 1 root root 14056 Jan 27 02:21 /usr/bin/lp.cups Looking for any ideas about what to try next. NB: I use Gnome, there is, and will not be, any KDE installation. -- (Currently running FC4, occasionally trying FC5.) Don't send private replies to my address, the mailbox is ignored.
