AirPrint stopped working after upgrade to iOS 12.0 I cannot print from Notes on my iPhone 6s+ since updating my phone to iOS 12.0 and I get the following error: No AirPrint Printers Found. My bonjour printer settings have not changed, and my router settings have not changed. I have tried 2 printers so far: a Canon MX512 and a Canon MX452. I actually noticed the MX512 stopped working a few months back, although Airprint was definitely still working with my MX452 until the most recent update. Both printers work fine with my laptop. What could be the cause/how can I fix this?
I have had the same issue.  The only way, temporary at best, I could see the printer from my iOS device was to change the Bonjour name of the printer from the local network site for the printer.  Works once, and then same issue recurs, though.
