Parallel port not working

by tgahan / November 3, 2003 8:36 PM PST

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.

After I try the other BIOS settings for the parallel port, I find a PCI Parallel Port board, disable the onboard portand that fixes such. About 10 to 20 dollars which is cheaper than a new board. You seem to have found the printer and its cable works on the other port, so the port seems defective. Since you can't repair onboard ports for any reasonable amount, replacement is the option.

I've also used the USB to Parallel adapters if I ran out of slots.

Reload your mtrbd. drivers as well from the recovery CD or mtrbd. provided CD from vendor. Do this before buying another lpt card if that what maybe the last resort to fix this. You say nothing changed other than new HD and W2K pro but the system just didn't catch that right upon install. Its important as PCI bridging and/or buss mastering the mtrbd. drivers may conflict with MS provided similar s/w, sometimes its best to reload the W2K drivers from vendor. Return the lpt port to SPP as the printer likes that as the std. default setting, EPP/EPC(?) isn't needed for your model printer.

good luck -----Willy

In your orginal post you mention MSIxxxx something, that's Microstar. Thus goto the microstar support website. I suggest you www.google.com websearch for the model# you have and verify it and then click on the apporoiate hit. Then d/l the required drivers, they maybe 4-in-1 type or similar, but it should mention mtrbd./chipset drivers.

good luck -----Willy
