So I’m having trouble getting thishttp://www.sparkfun.com/products/10438 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 1/2", 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
