printer not working after 13.1 update

You mention you downloaded drivers from Epson. But according to Apple, you don't need drivers as this model is supported by Apple Airprint. Can you remove the drivers from your Macbook, then reboot, then try again according to these two articles?

I have a Canon multi-function printer/scanner purchased in 2010 and an Epson multi-function printer/scanner purchased in 2015. I would love for them to stop working to justify purchase of newer, faster, devices! But as I have advanced the MacOS over time, which each new MacOS I typically would remove the devices from the Printers & Scanner Preference Pane or System Settings, then download the latest drivers and software, reinstall, then add the printer/scanner back. Both print two-sided and scan fine. I have some older and newer Macs in use, ranging from MacOS Big Sur through Ventura. You can scan with either the manufacturer software or simply use Image Capture (a native Apple application). Sometimes the two-sided option is buried in a sub-menu, it is not always obvious, so the companies' user interface could probably be improved. Some of Canon's utilities stopped working (dating from 2010) because they were 32 bit, but the printing and scanning is fine and at least for my Epson (XP-820) which I purchased 8 years ago, Epson has continued to provide updated drivers and firmware and is still supporting the device with Ventura. Not to say yours is still properly supported, but you might try the complete uninstall and reinstall approach, that's what I have done.

Generally, the Printer needs to be using the Same Network Connection as the Computer.

Further, the printer needs to be connected to the Router via the 2.4 Ghz protocol and Not over the 5 Ghz.

At least my ET 2750Epson clearing make mention of this.

The Apple Machines I use all connect to and use the 5 Ghz protocol but the ET2750 connection is the 2.4 Ghz and prints , scans fine use Apple AirPrint

Generally, once the Router has Stopped broadcasting in the 5 GHz band - the computer will flip its' connection to the lower 2.4 GHz Band.

You may need to get into the Router to make sure the 2.4 GHz broadcast Band is set to Broadcast Only in the 2.4 GHz spectrum.

Otherwise if set to Auto - it is possible it can Still Auto Broadcast in Both 2.4GHz and 5 GHz

Sometimes the issue may be fixed by Removing the Printer from Computer.

Shutdown the Printer

Shutdown the Router

Restart Router

Restart Printer and re-establish an Internet Connection from Printer to Router

The previous Contributor makes some very good Technical observations regarding AirPrint.

Which should not require additional Third Party Printer Drivers

To compare, running an Epson ET 2750 Printer / Scanner and AirPrint works just fine without Epson Drivers.

Though, I did need the Scanner Driver in-order to Scan wirelessly
