hello there, i want to know the printer interfacing with 8051 i have interfaced it and it is working fine -but when paper is not put properly that time my machine hangs can u guide me what to do in such case is it related to BUSY signal????? pls reply
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.
thanx for ur help and suggetion and next time i will give details because i was accessing this site for first time thanx
