Failure to generate print previews..OS 10.14.

When try to to do a print or save to pdf from any application, e.g word, firefox, safari Mail, the app loops and doesn't terminate.

If I do a safe boot, teis doesn't happens for some time, but, will reappear in a few hrs.

I am running 10.14.6. It happend with or without an internet connection and on apps that are not accessing the internet.

Any suggestions.

If a simple reboot of your Mac doesn’t fix things, see if the problem still happens in safe mode.

How to use safe mode on your Mac - Apple Support 


Safe mode will often correct weird software behavior by forcing the OS to clear caches, do disk repair and other self-maintenance and housekeeping and temporarily disables third-party mods.


Does the feature work while in Safe mode?


You can exit safe mode by restarting your Mac normally, then reevaluate the problem.
