Printing from Evolution after upgrade from 20.10 to 21.04

Greetings. I have just migrated from UM 20.10 to 21.04, and things seem to have gone OK, except for one thing. Print requests from within Evolution, independent of printer, yield the following message.

Drivers have been updated, and I have checked to see that I can print using other apps, so I suspect that there is an interface issue with Evolution, but I am hoping that someone can point me to the real problem/solution.



Some nosing around yielded the following info about a fairly long standing bug. See .

I have confirmed that the work-around does allow you to print from evolution. Work-around is to launch evolution from a terminal using the following command - WEBKIT_FORCE_SANDBOX=0 evolution

So, I would not call this solved, but rather identified.
