Can't print to Epson ET-2750 on Big Sur 11.5.2

Exact same problem with Epson XP-7100 after updating to Big Sur 11.5.2. I've tried deleting all the Epson software and reinstalling multiple times. Sometimes I'll also get a "bad file descriptor" error if I try to continue through the installation. No issues printing/scanning from my iPhone/iPad or my various Windows 10 machines.

Frustrating.

Still not working. Although the 7100 shows up as a "Bonjour Multifunct" printer when I clck on the "+" button to add it, Trying either AirPrint or Secure AirPrint, the system tries to setup the printer then returns a "An error occurred while trying to add the selected device. Bad file descriptor" error.

I've tried resetting the print system, deleting all the Epson software, clearing the library cache, spinning a dead cat over my head 3 times, etc. but still getting the same errors.

Turn off printer and restart computer. Turn on printer and make sure both computer and printer are connect to same Network. Add Printer via System Preferences >>> Printers >> Add and it should see the ET 2750 @ least it does on my MBA M1 on first shot.

I got an email back from Epson. Unfortunately, it wasn't very helpful and in fact, some of the Mac config screens they mentioned were incorrect. I've provided them screenshots and a very detailed, step-by-step of the t-shooting I've done up to this point. (I did not bother to tell them about the cat since that's not an approved troubleshooting step in most states.)

My confidence level is low that this is going to get resolved without having to spend some hours on the phone with Epson and/or Apple.

I've had a couple of back and forth emails with Epson support. As it stands now, it's still unresolved and Epson's recommendation is for me to call into Epson and t-shoot over the phone. Since their phone support line isn't available on weekends, I haven't been able to follow-up with them. I'll just revert to using my iPad or Windows machine for scanning and printing for the time being.

As far as not hearing back from Epson, check your junk mail. They replied back to me within a couple of hours but it had gotten flagged as junk and I only saw it because I have a habit of checking my JM folder from time to time.

Thank you missym14! After seeing your post, I tried adding my XP7100 and voila! It was recognized and installed and printing is back to working. Because I really need the scanner, I went and redownloaded the complete Epson driver package and it again, failed. So I tried downloading just the scanning app and it installed correctly. However, when I went to use it, I got a "you don't have permissions..." error. Checking the executable in Finder, I noticed that "Everyone" only had Read access. I changed that to Read/Write and now it scans correctly.

I have no clue what changed. There was no change to my printer firmware nor any changes pushed out via Apple. It's these kinds of solutions I just have to chalk up to the "resolution fairy" paying me a visit while I slept. :-)

Epson WF-4740 - I too have spent hours and days trying to find a work around and want to throw my Mac, but I am waiting and hoping. So frustrating. I have to take my documents to my sister's Windows 10 machine to print!

Set it up as AirPrint. Using the exact same Epson in AirPrint and works just fine.

Oh, and my printer driver version is also now showing as 3.0.

Go figure.
