Some have reported good results with tracing paper instead of
transparencies.
Others swear inkjet is the way to go, as there is no distortion.
There seems to be a big variety in ohp transparency quality, but if you
already tried a few..
The fuser temperature is not that much different with other printers, but
the transport system might be.
I didn't know anyone outside Germany uses Target, how is the 3001 version?
I think about buying
it because anything better is unafordable, but haven't actually done any
tests on the new version.
I used to use 2001, and it was a nightmare compared to orcad.
