I have a small printserver running at my office that currently has 2 printers, hence 2 parallel ports. I wish to add a third, so I went out and purchased a relatively inexpencive Parallel port card. However it doesnt work. I have tried shuffling around various IRQs, however this has not worked. What would REALLY help me is an application that can ACCURATELY display the IRQs, DMA, and IO addresses for all my hardware devices, this would take the guess work out of moving the IRQs around on the NON plug and play boards. has anyone else here setup a printserver with 3 LPTs in an NT environment before?
