Default Re: Controlling the parallel port

the easy answer is no...

there are various ways to control the parallel port using C, but only in windows 98...

wints nt versions (NT 3, 4 2000 and XP) have as hardware protected mode, meaning that you cannot interface with the hardware directly.

you have to go via a dll file to control the hardware, this dll file must be running at ring 0 level privelages...

the easy answer is use the serial port, (com control is available) and if you want a parallel our make or but a serial to parallel converter
