I have it connected to my PC with a standard printer
cable.
Well, that won't work for me since I don't use pee seas.=20
There are "print servers". Litle boxes with a Centronics parallel port
At one time the better PC shops sold serial -> parallel (and the reverse)
converters. Little boxes containing a microcontroller and not much else
which let you hang a parallel printer off a serial port, or vice versa.
I guess they're no longer easily available (they were useful, and it's a
well known fact that, at least in the UK, PC shops don't sell useful
stuff). But it's not exavtly difficult to design one! And there must have
been magazine projects for these over the years (I think I remember one
in 80-micro...)
