First unplug all cables and plug them in firmly again, also try other USB sockets on the computer.
Assuming this doesn't help go here:
Select Windows Printer Driver.
I would be inclined to run all three of these in the order given, restarting the computer and trying the printer at each stage:
EPSON Advanced Printer Driver Delete Temp Tool Ver.1.00
You then select "EPSON Advanced Printer Driver for TM Series Ver", choosing the
one that matches your series number (not given). Read the information to ensure the download is right for your device and country.
EPSON Advanced Printer Driver Update Tool.
The first and last effectively do a bit of rubbish clearing, so might help.
How old is the printer?
Always pop back and let us know the outcome - thanks
