    So I’m having trouble getting this going.
    My configuration is
    Wires-
    Printer: Arduino
    Green: Digital 2
    Yellow: Digital 3
    Black: Gnd (the gnd next to VIN)
    Red: VIN
    Black: Gnd (the other gnd next to VIN)
    Power-
    I’ve plugged a 9V 1000mA supply and a 4-5.5V 2.6-2.3A supply into the arduino and got the same results.
    Arduino Code-
    I ran the sample code but get nothing (not even in the serial monitor)
    Results-
    The LED on the printer lights up, flashes twice strongly then settles to an intermittent weak flash. If I press line feed the paper advances ½", I don’t get demo mode at all.
    The Arduino is a Duemilanove which works (blink test runs fine).
    Anyone got any ideas? I suspect my problems lie on the Arduino side (since I see nothing in the serial monitor) and the printer side (is my power supply insuffic.? or something else?
    Cheers
