I emailed Epson, asking about a printer driver for Big Sur. Their reply (and a heads-up for any Epson owners):
Thank you for contacting Epson regarding your Epson SureColor P600. In reviewing your incident, it appears that you have opened one of our online knowledge base articles to help you in resolving this issue.
In response to your concern, please be advised that currently, there's no available Epson printer driver for your product for MAC 11.0 and we do not have the exact details to when it will be available.
I did some more looking, and found
this statement that only Apple Silicon macs are affected. I replied to Epson's original email inquiring about it and will phone Epson if I don't get a reply. Hopefully, my installed Epson driver will work.
I can find out by installing Big Sur on a clone and trying the printer (not to be done anytime soon). In the past, I used Apple's printing software (accessed via System Preferences > Printers & Scanners) and found that many features were missing. Consequently, I only want to use the Epson driver.
If the + signs are clicked to reveal more info, it is stated that a fix should be available by December, 2020.
