Phomemo-printer for macOS
Inspired by https://github.com/vivier/phomemo-tools
If you're on Linux, use the above repository which utilizes CUPS.
If you're on macOS, the Python pybluez Bluetooth drivers don't work (well) on the latest iteration of macOS (tested on Ventura 13.2). Instead, this repository uses TinyGo's Bluetooth package, which wraps Apple's CoreBluetooth to be able to communicate with a Bluetooth device.

Building & Installing
The script checks a folder for files (intended to be set up as a cron job), if there are any, sends them to the printer (if detected), and deletes them.
main.go, you'll probably want to edit some variables. I hacked everything together in a day for our specific case.
To inspect the possible command-line options, use
-dir [dir]customize the dir to scan (by default
-file [file]print only that image
-file is used,
-dir will be ignored.
To install as a
launchd service (mac's "cron"), copy the binary to
/usr/local/bin and the file
~/Library/LaunchAgents. Then, in a terminal, type
launchctl load com.brainbaking.PhomemoPrinter.plist.
