Parallel port

[VCPLUS]

I am a newbie to device driver programming. Could anyone
tell me how to write a parallel port device programming in VC++(Microsoft)I need to get the productIds of the printers that will be connected to the Parallel port. I would appreciate if you could provide me with sample code and/or links.

Thanks alot.
John.

Well John. You're need to use CreateFile(); or make
some assembler in you programm. the form is
_asm mov ax,bx something like this
then you just write or read from port like this:
in bx is an address of a port.
_asm in ax,bx
or
_asm out ax,bx
