Description of problem:
Printing doesn't work from any program (lp, acrobat, etc) (printer DESKJET-930C). There is only the following error in the /var/log/messages file:
hp[17324]: prnt/backend/hp.c 847: ERROR: null print job total=0


Version-Release number of selected component (if applicable):
It's happens on fully updated fc12 even if I updated hp\* and cups\* packages
from the testing-updates.

#rpm -qa | grep -e ^hp -e ^cups
cups-devel-1.4.4-4.fc12.i686
hplip-libs-3.10.5-1.fc12.i686
hplip-gui-3.10.5-1.fc12.i686
hplip-common-3.10.5-1.fc12.i686
cups-pdf-2.5.0-3.fc12.i686
hpijs-3.10.5-1.fc12.i686
cups-libs-1.4.4-4.fc12.i686
hplip-3.10.5-1.fc12.i686
cups-1.4.4-4.fc12.i686


How reproducible:
100%, at least for me.


Steps to Reproduce:
1. Try to print something using either lp or any other program e.g. acrobat
  
Actual results:
