Features

✅ Currently implemented:

• Bluetooth transport.
• Serial transport.
• Packets implementation*.
• Complete bitmap packet implementation (empty row, indexed row, bitmap row, repeat count).
• Event system (eventemitter3 based).
• Image encoding with 3 types of packets (empty space, bitmap, bitmap indexed).
• Heartbeat support.
• Print error handling.
• Reading printer info (model, mac, charge level, etc.)
• Writing printer settings (sound, auto shutdown time).
• Abstraction (call helper functions instead of sending packets).
• Local model library with printers features (printhead resolution, supported paper types ant etc.)*.
• Headless serial client for non-browser purposes*.
• Headless Bluetooth client for non-browser purposes*.
• Command line interface*.

🐞 Bugs:

• Timeout after print finished on serial connection (status check).
• Printer MAC address have wrong order on some printers.

⚒ Todo:

• Find out how to properly encode bitmap packet. I can't understand purpose of three bytes before "repeat count" byte.
• Implement rest of the packets.
• Support more printers (print tasks).
• Testing with more printers.
• The rest of what I've forgotten.

❌ Will not be implemented:

• Guess the label size by RFID tag - impossible without request to print.niimbot.com. API does not allow CORS requests.

  Example:

  POST https://print.niimbot.com/api/template/getCloudTemplateByOneCode HTTP/1.1
  Content-Type: application/json
  niimbot-user-agent: AppVersionName/999.0.0
  
  { "oneCode" : "LABEL_BARCODE" }

* Implemented partially or needs some tweaks.
