You should still be getting the SELinux deny on the printer since the
needed constraint wasn't in the policy.  I got an update on my bugzilla
and the constraint will be included starting with the selinux policy
2.4.3-1 rpm.

As for the usb://Lexmark/T630 URI printers without /dev/ in their URI
are not checked for file system permissions before the job is sent.
Your admin guide should specify that printers MUST be created with the
/dev/usb/lp* style URI.

trouble with your postscript document.  If you revert the config files
to their defaults do you still see that problem?
