Not exactly a printer problem, but related!

I have a Canon FB630P parallel scanner that still works well.

Recently due to IRQ conflicts caused by other devices, I had to remove the
dedicated LPT2 interface card and change to a pass through connection to the
printer.

The parallel port now connects to the scanner and then from the scanner to
the printer. This works fine for printing (never a problem), but if I use
the scanner, it works just once. Then the scanner software reports that the
port (LPT1) is in use. (The Parallel port may be used by another
application. Error code 0x0006080).

If I try to use the printer, it works normally - no error message.

It seems that the printer or the scanner does not release the port properly.
If I shut down completely and then restart, I get to make one more copy and
again the port is in use. Making copies is a slow process!

The printer is a Deskjet 870cxi.

O/S is Win2K.

Any suggestions for a cure or work-around would be appreciated.

A Guess is that the printer status monitor is causing a conflict problem.
You may be able to determine what module is used for status, and disable it.
