The 3.3 volt parallel port output could be the problem if your BoB / Driver is expecting a 5 volt TTL signal.

What make and model breakout board / driver are you using ?

Hi,
if you open Device Manager I would expect to see Machs parallel port as a physical device.. something like 'Mach Pulse Engine' or similar.
It is one of the indications that Machs PP is NOT in fact a parallel printer port but is in fact tied to some very tricky low level software competing
with or at least in co-operation with Windows Kernel.
