Small modification of existing page.

The documentation at

https://help.ubuntu.com/community/NetworkPrintingWithUbuntu#Printing_from_Ubuntu

under the heading

Printing from Ubuntu

indicates that either either the host ip address or name can be used in printing to an Ubuntu print server. In my experience, printing from Ubuntu 12.04 to a server running on LinuxMint13, the hostname does not work although using the host ip works fine. I think that adding a correction, or at least a caution, might save some one from wasting time trying to use the hostname as I did.

Thanks,

Mike
