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.

Practical ARIA Tabs

This is a small guide to marking up fully accessible tabs. Consider using PostHTML ARIA Tabs as a practical solution.

The Rules

1. Add tablist role to the <ul> to indicate it contains tabs.
2. Add presentation role to each <li> to bypass its list item state.
3. Add tab role to each <a> to incidate it is an actual tab.
4. Add href and aria-controls to each <a> to reference its tab panel.
