I am trying to hook up a Canon Selphy CP1200 via USB but just can't get it to work. I can see the printer when I run lsusb ... Bus 001 Device 016: ID 04a9:32b1 Canon, Inc. SELPHY CP1200 but I don't have the option to install it as a printer. I have tried using both the gnome printer manager and Turbo Print. Both have drivers for the printer but they can't seem to detect that it's available. Is there a way to point my system to that USB device specifically? I have gutenprint 5.3.1 and CUPS 2.2.10 installed
I ran journalctl --follow and then plugged in the printer. Here is what I see

I finally figured out the problem. It seems that it was a conflict between CUPS and lpusb. The solution was to disable lpusb by running
sudo rmmod usblp. I'm not sure if this has and negative side effects, but it seems to have solved my issue. Once I did this I was able to go to http://localhost:631 and add the printer. There are some details about this problem here https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=545288
