I'm also getting the issue where Evince freezes when I open the print
dialog.  I have two networked printers which work fine from any other
program.

More background I can offer: I had this problem once before on this
machine and I solved it by adding/changing some user permissions, but it
came back after a do-release-upgrade to 22.04 and I can't seem to find
the original instructions for the solution again.  It was something like
adding a particular user permission to a particular config file in
apparmor.  The first time I found the fix I was grasping at straws and
found it in an odd way, maybe from a much older version of Ubuntu.

I'm using Ubuntu Unity 22.04 with Evince/Document Viewer 42.3  Here's my
very similar relevant output from dmesg | tail showing apparmor denying
something to evince:
