Was that the one that was fairly similar to Centronics but with some
signals inverted?

I have never heard of an Epson interface board for it, but it would not
surprise me if one existed. Wouldn't have to come from Epson, the
interface connector was documented so third parties could make their
own interfaces.

Incidentally. some of the RS232 interfaces for these printers did 20mA
current loop as well.
