I've been down this road with both P800 and P900 - they both have the same issue (also theoretically their smaller versions).
These are the possibilities about what happens. (and also the right "solution" for full printing capability).
- You install the driver, you follow the recommendation to enable AirPrint, and you're stuck because you Don't Have All Of The Printer Driver Controls. (so this would be bad). You can't really print properly this way; not the way you know you can. Lots of things missing.
- Having done that, what's your recourse?
- I'll skip to the easiest fix first, because it's guaranteed to work, and make you whole. (I know this, because I've done it). Connect the printer to your router over Ethernet. In OSX printer settings, click to add another printer, and add a new P900 printer using the IP (network) protocol. That's what you're going to use! It has everything you expect to see in a direct USB-connected printer instance, and it'll work, perfectly.
- Or, (so much fun), you can delete the AirPrint-enabled printer instance; reinstall the Epson printer drivers; go back then to the first step and DON'T enable AirPrint. Now you have a printer instance that connects to the printer over USB, that's right, the way we always used to. (and again, now you'll have all of the printer controls available, etc, just as described above for the IP printer instance). The question is: "will it actually work".
- I'll just mention that question, because: it may not. I've set up a P800 on a 16" M1Max MacBook Pro that way (and also, a P700 on a different 16" M1Max MacBook Pro), and it printing over USB, through the normal driver with AirPrint "not configured", did NOT work for me. You set up the print from Photoshop (latest version), everything is configured correctly, but when it starts to print, it stalls right at the start of the printing process. No amount of exhortations would fix this. (I think at first this would have been running Monterey last year; but I've seen that system again running Ventura and it still wasn't working). Using an IP instance for the printer on those systems were the only way to properly print.
