I had a network printer to replace with a new model of a different brand. This should be easy with just downloading the driver, add it and done.
Not so much. I get this dreaded error!
The “easy” fix has been to delete the printer and then re-create it with the new driver. I’m not sure this ACTUALLY works as the driver won’t “roll-down” properly to all the users connected to it.
SOLUTION:
As it turns out, the Actual Easy Fix is to disable sharing of the offending printer, click Apply, then update the driver. Once that’s done, enable sharing again. Voilà Tout!
