It's been a long time, but try holding down the LF button while
turning the printer on.

One of those combinations -- I think it's holding down both -- puts the
printer in 'hex dump' mode where it just prints out the hexadecimal values
of everything sent to the parallel port.

It was handy, some twenty years ago, for debugging software that was trying
to print graphics.

(Anybody else remember some of the BASIC example programs that came with
those old Epson printers? Some of the graphics patterns they did were quite
impressive...)
