  • 80451 is the microcontroller and printer interfacing is centronics
    i have resolved the problem as it was stuck in the while loop which i was using for 'print complete' screen now i have removed the screen and while statement and now it is fine. i hav just added 'sent to print' screen. it is related to paper out signal but we are not using this signal now.
