As you only upgraded from Catalina to Big Sur then the printer drivers will still be installed.
Won't hurt things to reinstall them and see if it makes any difference.
Have you contacted Epson to see if they are going to update the drivers for the TX710W.
As Big Sur is a very new OS it may take time for manufacturers of printers
etc to release updated drivers, if they are going to.
If you are thinking of buying a new printer you will need to make sure it can operate
in Big Sur, most of the ones you will find in store would have been manufactured before
Big Sur was announced so may not have any indicators on the box saying if it is compatible
with Big Sur. So be very careful. Do your own research, do not trust store staff.
Epson make a very similar printer to yours called the PX710W, this printer does have
a Big Sur driver. If it were me I would download this driver and see if it works with your TX710W.

When the download finishes double-click on it to install, restart your mac, connect your printer
and see if there is any progress.
