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.
If you are going to send text to a Centroncs-connected printer, you really have to care about this signal. You may loose your printout if the printer is off-line. Also laser printers or ink-jet printers may run out of paper, or the user may manually have set the printer off-line and forgotten about it.
