It should be an "RS-422" interface AFAIK.

Normal NetBSD/mac68k drivers use the normal mac serial ports, which are
RS-422.

Since the printer works under MacOS, I suspect the problem is either
that you are using the wrong baud rate, or the printer doesn't work in
text mode (which would be suprising).

What baud rate are you using?

Take care,
