hap, yesterday you've added the following:
"smartboard: add support to connect it to pc printer port"

How can this be used or tested?
I don't see anything wrt. printer or centronics in any menu, not in MAME and not in Tasc R30 either ...
Does this require a real PC printer or can this be emulated in MAME?

For the Novag SuperForte you have mentioned an option "-rs232 terminal" long time ago, so I've now tried it for the TascR30 with options like
"-centronics", "-printer", "-lpt1" etc., but nothing worked.
