CUPS not printing to network printer.Printer visible to avahi and cups

Hey. Printing seemed to be working fine last time I checked (which, granted, was a while ago...I don't print that much). I have a networked Canon MG4100 class printer. Avahi sees the printer just fine, as does cups (I can add and modify the printer without any troubles). However when I try to print, it starts printing but then the Cups interface notifies me 'Unable to locate printer "canon.local".'

1. The printer works fine from a windows laptop
2. I reset the printer and the wireless router it's attached to
3. I restarted my laptop
4. Here are the /var/log/cups/error_log (debug level) logs
5. /etc/cups/cupd.conf
6.

10:06:50 $ avahi-browse -atl
+  wlan0 IPv4 Canon MG4100 series                           Web Site             local
+  wlan0 IPv4 Canon MG4100 series                           _scanner._tcp        local
+  wlan0 IPv4 Canon MG4100 series                           UNIX Printer         local
+  wlan0 IPv4 Canon MG4100 series                           _canon-bjnp1._tcp    local

7. journalctl -b -u cups

8. Oh, and I tried downgrading cups and cups-filters to the previous versions from the beginning of September. Same issue.

What the heck am I missing???

Thanks!

Re: CUPS not printing to network printer.Printer visible to avahi and cups

Maybe this helps.  Try a different URI by modifying the printer in CUPS first.

Re: CUPS not printing to network printer.Printer visible to avahi and cups

I'll look into that when I get a chance. I'm just using the Gutenprint drivers. They were working fine up until recently...I just don't know at what point because I rarely print! I'm a little leery of adding the printer with a static IP address, because it's not a static IP setup...I know it should stay the same for the most part, but I thought that's why we used Avahi...to get away from having to know the IP address!

Thanks for the input!

Re: CUPS not printing to network printer.Printer visible to avahi and cups

I got my printer working with the official Canon printer drivers.  Can be a little tricky to set up, but works great.  My URI with the official drivers is cnijnet:/00-1E-8F-A6-5A-72
