I need to be able to run a silent print from an Air app to a custom printer size. I haven't been able to select a custom paper size but was able to at least make it work by setting the default printer with the correct paper size set as the default as well. In Mac I am unable to do this. How can I set the printer and paper size so that I can prep and send the print job silently to the printer?
I don't know much about configuring printers but you might be able to run your app using the nativeProcess API and set the default printer via a shell script:
