Hello,
Thank you for the information.
Latest update installed on my iPhone, iPa… - Apple Community
The Epson ET-2760 and Canon MF644Cdw are listed in About AirPrint - Apple Support.
AirPrint-enabled printers can be used without additional drivers, provided that the printers and the Mac computer are connected to the same network (Wi-Fi router).
Printing from an iPhone or an iPad is also possible (without an additional app), if these devices are connected to that same Wi-Fi network.
Use AirPrint to print from your iPhone, iPad, or iPod touch - Apple Support
You may have tried to reset the printing system and re-add the printer to use AirPrint. If necessary, please see the following links for details.

The router is important in this context. If there is a problem with device discovery in connection with AirPrint, the following power-cycle procedure (in this order, with the waiting times) can be tested:
Power off the Wi-Fi router, the printers, the Mac, the iPhone, the iPad, and all other devices/computers. Wait two to three minutes. Power on the router. Wait two to three minutes. Power on the printers. Wait a minute or two. Power on the Mac. Power on the iPhone and the iPad. Finally, power on all other devices/computers.
