Thermal Printer TX unresponsive

Post by steveblair »

A while ago I bought one of the Thermal Printers that Adafruit sells (https://www.adafruit.com/products/597) and managed to get it printing messages with an Arduino whenever a button was pressed. Since pressing the button multiple times resulted in several messages printing, I used the SoftwareSerial available() and read() to check the printer's paper status. It was working flawlessly until tonight when it suddenly stopped printing at all. A bit of troubleshooting and I've found that both available() and read() are returning false. My wiring is fine, and I've tried switching ports on my Arduino. Has anyone else come across this? Is it possible the printer's TX port just died?
