Network printer is not accessible

I am using OpenSuse 13,1, KDE and NFS netWork

After installing OpenSuse 13.1 on a terminal, the network printer is no longer being accessed.

I tried to remove and install the CUPS package. Using APPER.
This made the network printer to be accessed again by this terminal

But the next day the printer was not accessible.
I removed and installed the CUPS package and again returned to work.

I have always done it, without discovering the cause, but now, CUPS package is not being installed.

APPER The program shows the entire installation process, no error messages, but does not install CUPS again

I can install CUPS, with the '# zypper install cups "command, but the network printer is not accessed

Please, any suggestions?
