As you've installed CUPS, the commands lp and lpr are both used by CUPS as front-ends to their system. Look at "man lp" and "man lpr": you'll see that the pages are written by "Easy Software Products" who make cups. Red Hat has been implementing a Debian-like "alternatives" system for a couple of things like printing, mail since 7.3. Examining /usr/bin/lp with a "ls -l" will show that it's a symbolic link to /etc/alternatives/print-lp which is a symlink to /usr/bin/lp.cups which is what your "man lp" describes the behaviour of (sorry for the bad grammar!). Similarly for lpr. > > I upgraded from Red Hat 7.2 and printing worked fine under 7.2 > > Another example: I' running gv and try to print a page using "kprinter" as > print command - kprinter says, that my file has been sent to the printer and > nothing happens anymore... > > Maybe any idea? Make sure that you run "redhat-switch-printer" to make sure that CUPS is indeed chosen. Try setting the Printer options in "gv" to something like "lp" or "lp %s". Use the http://localhost:631 CUPS administration interface to print a testpage to make sure that CUPS is indeed seeing the printer (alternatively you could use the lpadmin commands that CUPS introduces if you prefer the commandline).
