Hello,
My name is Mihai and i have recently bought a mini thermal printer like this:
http://www.adafruit.com/products/597
I have connected it to an Arduino One and run the printertest.pde tests, but all I get are just some dots.
These are some images with my wires connections and the printing result:

I would appreciate very much if you could give me a hint about what my problem is.
It could be a problem with the printer?
Thank You,
Mihai Cracan

Re: Mini Thermal Printer print only blurred dots
It looks like you are powering the printer directly from the Arduino. The printer requires more power than the Arduino can provide. You will need a separate power supply with at leas 1.5A for the printer. http://learn.adafruit.com/mini-thermal- ... nter/power

Re: Mini Thermal Printer print only blurred dots
It seems that this was the problem. I have added an external power supply and it printed something, but unfortunately this was the result:

All I have available for now is a 1A power supply, so I have powered the printer with 1A.
Could be this the problem or is something else that caused it?
Thank you!

Re: Mini Thermal Printer print only blurred dots
It looks like you have more power to the printhead now. Not sure about the strange characters.
Was this a printer you purchased from Adafruit? There are other models based on the same printer chassis that have different firmware or default settings.

Re: Mini Thermal Printer print only blurred dots
One of my local shop helps me to get it from Sparkfun, but I was thinking that all of them are made by Adafruit. I found some code examples on Sparkfun too and I will test them.
On this occasion let me thank you for these great products that you made. You really do some great work here.

I have tried with some libreries from Sparkfun but unfortunately I got the same strage characters.
My printer model is CSN 2 T, the same model as on Adafruit.
Thank You.
