iMac can't access EPSON wifi printer

Hi there I hope someone is able to help please,

I have a 2017 iMac connect via wifi to an EPSOn XP-720 printer/scanner. Until this week I had no issues in printing and using Vuescan software for the scanner. However now I can't print/scan from my iMac, although I can print over AirPrint from my iPhone and iPads.

I have purged the old settings in MacOS, reset my route and the printer, deleted the printer from my router table and attempted add the printer again where I an for some reason faced with two options (same image) where when I installed the printer from new there was only one.

Attempting to install either after a few minutes showing setting up "EPSON....._ I get the error following error!

Can anyone point me in the right direction please, I have the same issue when attempting installation using other Admin users on the iMac.

Thank you for any suggestions submitted.
