Parallel port not working

by tgahan - 11/4/03 4:36 AM

I installed a new HDD recently and reloaded Windows 2000
Pro. I have two parallel ports, one on-board (LPT1) and
the other (LPT2) is on a card in a slot.
When i attached my printer (HP 840c) to LPT1, the computer
did not detect it. I manually installed the win 2k printer
driver and still the printer was not detected.
When i connected the printer to LPT2, the printer was
detected immediately and functioned as normal from this
In device manager both LPT1 and LPT2 are listed as working
correctly and drivers are installed.There are no conflicts
betwwen the ports, LPT1=0378 and LPT2 = 0278 (IRQs).
I tried changing the port mode for LPT1 in the BIOS from
SBB to EPP mode and the printer started printing symbols
and kept feeding paper instead of printing a single page
plain text document i was using for the test when
connected to LPT1 (NO problem printing from LPT2) .
I uninstalled LPT2 completely and restarted the PC and still LPT1 would not work, but is listed in device manager as working correctly.
How can i get the port (LPT1)working again.
