I’ve been messing with the Pipsta mini-printer that connects to the Raspberry Pi. I wasn’t sure exactly what I wanted to do with it so I decided to learn how to send messages to it via the web. To do this you need to use the example software that comes with the printer and runs on the Raspberry Pi, a third-party MySQL server, and a little PHP.
To start, you have to set up your Pi to ping an addressable database. You can learn how to do that here. You can then then set up the server to receive jobs from the database and test it by sending a few jobs via the command line.
