I updated a machine to Safari 16.6 yesterday, and discovered this issue. Same behavior as described here, sessions just seem to eventually disappear.

Even in the 11.0.1 release, I'm having this same issue. I've narrowed things down a bit to some specific behaviors: AirPrint driver seems to print OK, as long as I'm only using 8.5 x 11 (letter) paper. I cannot print on any custom sizes, or things like envelopes. Using the native printer driver and connecting either via Bonjour or direct by IP, no text prints, only graphical elements. Custom page sizes, and envelopes can be printed, as long as I don't want to print text. I've reset the printing system multiple times, made sure I have the most current print drivers, and nothing seems to work.
