I am developing an input/output device using parallel port and logix4u's inpout.dll
Im using WinXP.. the software side is good under vb.net.. =)
But I am having a hard time searching the net about the hardware side.
I need more info's about it because I am really interested. What is the voltage and current produced by the outputs?
What is the voltage and current required by the inputs?
Making a mistake will harm my system..

We know that new printers supports usb instead of parallel ports.
I want to use a parallel to usb adapter because usb ports are everywhere can I use the usb instead to produce the same output as parallel ports?
