Big Sur hangs when printing

[Marty Knapp]

This BigSur printing bug happens when you "open printing with dialog” and has been confirmed by Panos. Drop the “with dialog” and you can print. I don’t know at this point if the issue is with LC or with Apple. In the event that it doesn’t get fixed by the time BigSur is released, I want to have a stand-by work-around by creating my own print dialog. 

I see that I can get a list of all the installed printers and can get the currently selected printer - easy enough to take care of printer selection. What I don’t seem to be able to do is access any “Presets" that the user may have configured (paper tray etc). Is that out of our reach? printerFeatures and printerSettings do not seem to cover it.

I’ve had several customers report the same issue. This is making me really nervous as I would guess the Big Sure release is going to be here very soon. I have a mission critical app with printing as an absolute necessity. Try it for yourself - create a stack in the LC IDE and then try to print the card. The print dialog never appears and it will hang. I was able to successfully print from a couple of Apple apps with no problem.
