We too once had a device that plugged into the printer port
with a pass-through for the printer (it was the Covox Speech
Thing - a speech synthisizer in the MSDOS environment) and we
also had printing problems.

In the end it was determined that the problem was degridation of
the signal due to the pass-through combined with long printer
cables. As the output to a parallel printer travels down the
cable, the signal degrades (which I presume is caused by
bleeding and loss of signal strength). Consequently, standard
parallel cables are manufactured to the presumed maximum length
for reliable operation.

The problem was solved by having a cabling company makes us
some short printer cables. Obviousely one can't expect users to
replace their printer cables so what's the solution when using
a dongle?

Well, I would imagine that the quality of construction would
impact the signal so choose a vendor well. The only other thing
that comes to mind is if there are serial dongles available (of
which I have no clue).
