#include "conio.h"
#define DATA 0x378
#define STATUS 0x379

//for writing
_outp(DATA,4); //where 4 is to be written to data port
//for input
_inp(STATUS);

/*the addresses given are the common ones for the DB25 parallel port. Data or output port is an 8 bit port white status port takes it as an 8 bit data but allows only 4 or 5 input pins. Refer-
