Canon printer gone strange.

I recently upgraded my Late 2012 iMac from El Capitan to Mojave. Everything went well with no obvious problems and it is behaving much better with far fewer spinning balls and no lock ups which were happening most weeks requiring a hard restart. However my Canon MG8250 Inkjet is behaving oddly, a black and white print comes out in shades of green, and colour prints have distorted colours except for blue skies which look OK. I have tried uninstalling and reinstalling the printer, and also run the cleaning routines on the printer, also replaced all the cartridges, with no improvement.
Is it possible that the driver in Mojave could be wrong for this printer? I can’t be certain that the fault appeared After the upgrade but think so.

Just thought I should update, the problem was due to the printer, nothing to do with the update to Mojave, altho' the Canon helpdesk said the MG8250 is not supported in Mojave, "First of all, we would have to inform you that this model is not supported on Mac OS Mojave 10,14 and later, which means that it is not supposed to function with it, at all."
With their advice I have resolved the problem.
