Hardware quirks
Read before integrating
QL-820NWB and QL-820NWBc share PID 0x209d; this entry covers both marketing names. Bluetooth on this device is classic SPP (paired at the OS level via RFCOMM), not GATT — the runtime serial implementation opens the OS-paired RFCOMM device path. macOS dropped classic Bluetooth SPP support so that route is unavailable there; Linux and Windows both work.
Reference test device. Two-colour printing on DK-22251 confirmed, auto-cut works on USB and TCP, WebUSB demo prints correctly. The QL-820NWB and QL-820NWBc share PID 0x209d; this entry covers both marketing names.
