Dear Ashwani,

I do hope that Abhishek's assumptiuon is correct.

If so, you dont really need a 8255 to handle just text printing using the default font. A basic implementation without checking for paper out / printer powered up etc is really simple.

The code for directly using the port pins ( via some buffers of course ) was posted by me in response to a thread that started exactly like yours...

Please use the search for the topic and if you still dont find that thread and mail, drop me a line.
