I have two Suse un-firewalled computers connected via NFS. About a year ago I found instructions for a very SIMPLE way to share a CUPS connected printer using Yast. When I installed 11.4 I lost the instructions. It required no config file editing and took about two minutes. Google searches focus on complicated SMB-Linux connections like those suggested by swerdna. Does anybody know where I can look for help?
Very simple, use YAST to configure the printer on one of the Suse boxes and enable sharing, the other system will see the printer via cups broadcast. NFS is Network File System
which allows mounting of network volumes off a NFS server.
Samba can also share a printer with windows but unnecessary when using only Linux.
As dwellen has already suggested, CUPS can be used to share printers across local networks (on the same subnet) without issue, via CUPS browsing. I frequently connect to an epson printer running on a Mac at my parents house. As both Linux and OS X use CUPS, my laptop ‘discovers’ the printer automatically (without configuration).
CUPS uses IPP (Internet Printing Protocol) to do this.
