Tiny Thermal Receipt Printer - unresponsive

Post by and_how »

I recently received an order from you (invoice #699186).

Unfortunately I am having issues with the following item:

Tiny Thermal Receipt Printer - TTL Serial / USB

This device is not working as expected. I have tried to connect it to the Pi via USB and have also plugged it in directly through a USB power adapter but the device is completely unresponsive.

I have followed the troubleshooting listed for the Mini Thermal Printer as detailed here: https://learn.adafruit.com/mini-thermal ... leshooting

I have also followed the relevant advice within the thread here: viewtopic.php?f=19&t=146423

Running the command:

dmesg | tail -20

shows no updated results when I connect the printer to the Pi via USB.

Please let me know if there is any other guidance you can provide or if the unit needs to be replaced.

Thanks,

Andy
