I has been using MacBook since 2018 without any issue with printer connection. Ever since I updated my OS to Big Sur, my MacBook failed to link with no only Cannon Printer but also HP Printer. Please help and advice. Thank you.

I have 10 iPads of diffrent ios versions an modells connected Canon selphy cp1300. Since the release of ios 12 all iPad have been reciving timeouts. The more phones around the iPads the more timeouts. Using my ipad for photobooth. So there is a lot of people around them. I still have 4 iPads with iOS 11 that saves my side business.
