Unable to locate printer error with cups+avahi in Slackware64

Two weeks ago I installed Slackware64 on a new ssd. Previously I had been using 32-bit Slackware. This past November I got a wireless Canon MG3620 printer. In 32-bit Slackware I added avahi and nss-mdns from SlackBuilds, then recompiled/reinstalled cups with avahi and mdns enabled. After that the printer was working great.

Today I attempted printing for the first time since the install. I have already installed avahi,mdns and recompiled cups as I had done previously. The printer is discovered correctly with a dnssd address. However, when attempting to print anything (even a test page) the cups web interface always gives the error "Unable to locate printer "919B80000000.local"."

I have been searching Google and various forums all day for ideas. I have copied the working cupsd.conf and nsswitch.conf from the old disk, checked /etc/hosts and everything in /etc/cups, and ran avahi-resolve with the printer's ip and name to verify that it resolves both ways. I have deleted and re-added the printer in cups many times, and recompiled cups again.

Just now added it again using ipp with the ip address and it does work this way. Any ideas why the dnssd is failing?

Never mind, I solved this one. I had to add the printer's ip address and the 919B80000000.local name in /etc/hosts. Odd because I didn't have to have that before...
