- Use thickness command (10 FF 10 00) instead of density (1F 70 02) for P15
- Wait for initial BLE credits before returning from connect()
- Prevent info queries from interfering with active print jobs
- Send preamble commands separately, wait for credits before bitmap data
- Remove unnecessary image padding to print head width - send at label's natural pixel dimensions matching the official app (4x less data)
- Add detailed flow control debug logging for diagnostics
