EPSON ET-7700 does not show up in printer list

When I searched the forums for printer drivers, I was encouraged to see a couple of responses ‘worked out of the box on PureOS.’ Sadly our new printer does not show up in the list of printers at all. I tried downloading the drivers from Epson, despite the warning ‘Epson does not support linux.’ As others have mentioned, those drivers rely on the lsb package, and having lsb-base and lsb-release does not pacify them. Any suggestions before I reach out to customer support would be appreciated.
