Yup, tried all the basic stuff including turning off the firewall just long enough to see if that was a problem. > Have you checked back for another firmware update. > Checked the status page on the printer itself.

I still think the problem is on the linux side as I can print from my phone just fine, which is what I had to do. Based on the name of the printer it finds I'm pretty sure it's using the dnssd path. I actually did finally get it working through direct IP address which was discovered automatically, which is weird, because it didn't find it by IP address during the previous 50 attempts. I guess that means I should probably reserve the IP address in DHCP so it doesn't potentially change. Thanks, Richard
