Description of problem:

In both a clean Fedora 15 install and an upgrade from Fedora 14, cups is unable to print on Xerox Network Printers. My problem is specific to Xerox WorkCentre 7232/7242. In Fedora 14 it was working fine. I have tested this with all the drivers released by Xerox. All of them work in Fedora 14 and none of them works in Fedora 15.

Version-Release number of selected component (if applicable):

cups-1.4.7-3.fc15.x86_64

How reproducible:
ALWAYS

Steps to Reproduce:
1. Configure Xerox Network printer with any protocol (socket, ipp, ldp,... doesn't matter, none of them will work)
2. Install any Xerox driver for the printer, or even a generic one.
3. Try to print anything.
4. cups responds "/usr/lib/cups/backend/socket failed" or similar all the time
  
Actual results:
Printer communication fails miserably.

Expected results:
Printing should work.

Additional info:
I have disabled SELinux to do the tests, but changes nothing. I have tested printing in a Canon Network Printer and it works properly.
