I have an HP Laserjet 4200DTN on LPT1 of a Windows 7 PC. The internal network card went bad and I've had it connected parallel ever since. It works fine on a Windows XP SP3 PC.
Cannot get a test page out of this setup. Installed the driver from HP's website.
The printer icon gets a yellow shield the instant I try to print a test page.
Tried a Windows Update from the printer install window and selected 4200/4300 series. same result.
Also tried to use the Universal Printer Driver. This creates a separate icon that is associated with nothing. During installation it said it could be assigned to a printer.
In device manager there are only COM ports 1 & 2 no LPT ports.
