Can you print any other files? Is the printer installed - can you print a test page using the CUPS web interface? If not, then you need to make sure it is running. What printing system are you using - CUPS or something else?
PS: RH9 is very old now, I suggest upgrading to a newer distro. If you are happy with Redhat, try Fedora (new version of redhat), the latest version is 5.
