I was asked by a friend of a friend to look at their computer... the person had spent 600$+ on tech support from companies who were unable to fix the problems. I was able to fix the first 2 but the 3rd stumped me. Here it is:
She has 2 printers and one zip drive. To run these all at the same time she installed another parallel port. A HP 4ML is running on one port and a Lexmark w/ external zip is running on the other. The lexmark and the zip work correctly but the HP will not print when sent jobs it just times out. I have tried swapping out all the cables and the lexmark works when used on the port the HP is connected to and the HP works on a different computer.
To get this to work before they had to have a tech come and "trick the printer into thinking it was something else" and she said he did it in the device manager section. The only thing i can figure the tech had them change was the IRQ. Any ideas?
Thank you for your time,
