Have you installed any anti virus checking software? Get rid of it.
I did a google search on "Sudden Problems with printing macos" and I didn't find many instances of the problems.
-----------------------
I recommend etrecheck to assist in sorting out performance
issues.
I'd run etrecheck. Etrecheck will analyze your
machine and software and generate a report. Post results here so
others can view. Experienced users have found the reported
information useful when diagnosing problems. The proprietary stuff
in the report gets filtered.
Install and run
-- Download etrecheck. Goto the EtreCheck
download page. The download link is at the bottom of the
screen
-- Install etrecheck. Goto your download folder. Double click on
EtreCheckPro.zip
-- Drag the app to the application folder if you wish.
-- Turn on full disk access for EtreCheck. This was how
macos used to work. Do it for etrecheck not avast as in the
instructions.
