  • Printers without a bulk IN endpoint (most label printers) now connect.
  • Vendor-class (0xFF) printers are listed and connectable; non-printers (storage, HID, hub, audio, video) skipped.
  • Fix crash when the device can't be opened; connections no longer leak on claim failure or reconnect.
  • Ask for USB permission and wait for the answer on connect/write/print instead of reporting "not found".
  • Connect and write run off the main thread; thread-safe connection cache; exact-match cleanup on detach.
  • A zero-byte transfer no longer loops forever; a failed write drops the connection so the next print reconnects.
  • Every method replies exactly once (printText null, bad base64, unknown methods); disconnect when not connected returns true.
  • Receiver registered once and unregistered safely.
  • Windows: getUSBDeviceList lists installed printers (default first, with printerName, port, isDefault, isOffline); connectPrinter(name) selects one and write / printText / printRawText send RAW spooler jobs. Pure Dart (win32), no native code.
  • New: queryStatus(query, {timeout}) returns the printer's status reply (null when unsupported).
