Thermal Printer Won't Print a Test Message

Post by FerranC »

Ordered Products:
Mini Thermal Receipt Printer[ID:597]
Thermal paper roll - 50' long, 2.25" wide[ID:599]
Panel Mount 2.1mm DC barrel jack[ID:610]
etc...
I basically had the same issue as the guy posted before: http://forums.adafruit.com/viewtopic.ph ... ode&state=
When i push the button, the printer moves the paper just 1-2 mm and doesn't print anything.
I did try flip the paper roll making sure it face correctly, but it still won't print the test message.

Does the paper fit loosely? Or is is a tight fit?
Can you post a picture of the paper in the printer?

I think the paper fit just fine, just a little bit loose because there is no holder for the paper roll.

Here is the picture

Can you get a clear picture of the connections on the back of the DC jack? Thanks.

So I change a power supply which is 5V 10A, and it still does not work with the same issue.
