AirPrint Problems with iOS 16.0.3

Why does my AirPrint no longer print the exact range of pages I instruct, nor print on the back of a page as it used to do before the update to iOS 16? I have used the same cannon MF644cdw laser printer for the past 3 years with AirPrint enabled and never had a problem. All are connected to the same WiFi and all software/drivers are updated. I have also experienced the latest online complaint of AirPrint being unable to locate an AirPrint printer when all are on the same WiFi network. This is a pain, especially when I try and print the latest page in a 30 page email stream. All pages get printed on just one side, even though the iPhone print settings are set for double sided printing and a range of just page 1 out of 1-30 pages. Any advice would be deeply appreciated!
