What is your parallel port cable lenght?? If it is more than 1.5 Meters, reduce it.
 

Have you used buffer like 74245 or 74244???
 

i didnt use any thing
i connected it directly with a network cable
 

Check your Addresses

Assalamo Allykum !

Check your starting addresses and the memory location addresses in the programe.
