An acquaintance needed a video kiosk that plays looping videos for an exposition booth. Since I have a bunch of Raspberry Pis lying around, I figured that it would be the perfect use case for using one of them.

Let's assume we start from scratch, with a unflashed, brand new SD card and your Raspberry Pi.

Installing the OS

Install a version of Raspbian that includes the desktop. You can head over to : https://www.raspberrypi.org/downloads/raspbian/ and follow the instructions.

Once the image is downloaded, you can burn it to your SD card with tools like Etcher (https://www.balena.io/etcher/)

Controlling the Brother P-Touch Cube label maker from a computer

The Brother PTP300BT label maker is intended to be controlled using the official Brother P-Touch Design & Print iOS/Android app. The app has arbitrary limits on what you can print (1 text object and up to 3 preset icons), so I thought it would be a fun challenge to reverse engineer the protocol to print whatever I wanted.

Python code at the bottom if you want to skip the fine details.

Process

Intitially I had a quick peek at the Android APK to see if there was any useful information inside. The code that handles the communication with the printer in Print&Design turned out to be a native library, but the app clearly prepares a bitmap image and passes it to this native library for printing. Bitmaps are definitely something we can work with.
