[Bug 1342271] Re: lpq has long hang before completion.



I use remote printers over CUPS server and I have the same issue on my
computers installed with Ubuntu 14.04 (no problem with Ubuntu 12.04)  :

$ time lpq printer
printer is ready
no entries

real	      1m0.082s
user      0m0.010s
sys	      0m0.007s

If you need information or if you want me to perform tests, don't
