I have a good reason for doing this, and I don't have anything more important I should be working on.
The reason reason I have this printer set up is for printing the shopping list. Printing from bash is a fun side effect of having a printer on MQTT.
When you hit the button it publishes a message. A service on the server polls #grocy for the current shopping list and publishes it out onto the print topic.
