I recently had to install a Multi I/O communications card into a customer's PC who needed a parallel port to print to. After installing the card the printer is not printing. I think it might have something to do with the printer ports. The current settings of the card in device manager is
COM3 (port1)
COM4 (port 2)
LPT3 (port3)
I have already tried installing the printer using LPT3 but it didn't work.
I don't know anything about COM and LPT ports can someone please help?
