Subject: [CAD_CAM_EDM_DRO] 3.3v to 5v Parallel Port conversion


> I'm interested in using a laptop with 3.3v parallel port output to drive a
stepper driver expecting 5v (or at least > 3.3v) output. Are there any
schematics around for such a conversion, or are there hidden dangers to such
a strategy? I'm hoping I can pull up each pin to 5v, but I lack the
electronic savvy to design such a circuit myself.
