I’ve connected my Epson Stylus C82 to the Linux box and I’ve set up CUPS to allow browsing & remote printing. It took a few hours of trial and error, but I’m now able to print to it from any of my Macs.
The changes to /etc/cups/cupsd.conf were to add the commands:
Browsing On
BrowseAddress 192.168.0.255
BrowseAllow 192.168.0.*
Also, for any areas which limit access to 127.0.0.1, I added ‘Allow From 192.168.0.*’.
