Hello,

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

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

This solution works for me : in /etc/cups/client.conf we added /version=1.1 to the server address :
ServerName printhost.yourserveraddress.com/version=1.1
