Test print page stuck in spooling

Hi all,

One of our users added a shared printer to their Windows 11. Tried to print a test page and this is now stuck in spooling.

Interestingly, Print Management shows no jobs pending but there’s a job stuck in the printer queue. No jobs visible in the UCS Print jobs.

I tried restarting CUPS, samba4 all to no avail.

Any ideas how to purge this test page?
