Dos mode programs cannot see the usb port on your local computer. Remember full
support for USB didn't come until win98, but not in dos mode. There are a few
printers out there with both ports still. The HP Deskjet 5550 has both ports
built in and works well in 4.5++. The commands below should work if your
printer was being shared on a different computer

This is a neat program for printing from DOS to a USB printer:

It even has a 30 day Free Download for testing.
