Virtual USB port

[wahid95]

Hi,

I got HP Deskjet 3845 printer, it installs using a virtual USB port. I have one application which is not able to print on a Virtual USB port, it generate error. Any idea to avoid install of this printer on a virtual port or any other idea...

Regards,
Tayyab

You can try this:

Set up your application to print to LPT1: (or an unused LPT port on your system.)

Turn on printer pooling, so that the printer resides on BOTH lpt1 and the USB port.

When the application goes to print to LPT1 (assuming it does it properly, and not with hardware calls), Windows will think that the LPT port is busy (since there's nothing connected to it) and re-direct to the USB port instead.



Just my $0.02
