hello, i have a thermal printer that runs on a parallel to serial mull modem cable, im trying to figure out how i could do a simple circuit to put led's in line with the cable and have them turn on and remain on when a print job is sent, then to turn them off i would like to press a button, you know, kind of like a confirm i picked the printed paper up type thing.
im thinking 555, and thats about all i know.... what pins or such should i use and what type of curcit could i use? anything i can lookup, because im not good with doing things from scratch...
thanks a lot everyone!
cheers
