Comment # 8 on bug 1052793 from Antonio Larrosa

Thanks for all the information, Eric. I prepared a Qt package which completely
removes the remote printer discovery patch just to check that that's not the
reason of this problem as Fabian requested and also added some debug output to
see the available printer names and what is actually being selected in the
print dialog. Can you install it with the next command?

Then run okular as you usually do and try to print a document. Can you attach
here the full debug output?
