USB and parallel printer

I've got a USB printer (canon MPC 190).

How jetdirect works? Are USB printers supported under PXES?

Can I just plug in any printer and then tell my windows box
that it needs to go to IP:PORT to find a Jetdirect server, and
install the correct driver on windows?

I tried to share it with jetdirect but:

1) The usb printer module is not loaded at PXES boot.
2) Which device file should I use with it? /dev/printers/0?

thanks in advance
