You must set your lpt port addres for LPTx name. Use following program:

#include <stdio.h>

void setlpt(unsigned int num, unsigned int port)
{
        unsigned int _offset;

        if ((num =3D=3D 0) || (num > 4))
                return;

        _offset =3D 6 + (num * 2);

        printf("Setting LPT%d to 0x%X\n", num, port);

        asm {
                mov ax,0x0040
                mov es,ax
                mov di,_offset
                mov ax,port
                stosw
        };
}  =20

int main ()
{
        setlpt(1, 0xEC00); //set LPT1 to be at 0xEC00
        return 0;
}
