  • New PrinterReadiness / PrinterStatusQuery (TSPL <ESC>!?, ESC/POS DLE EOT 4) and checkStatus(job) on Bluetooth, USB and network managers.
  • BluetoothPrinter.battery and connected.
  • USB (Windows): native memory and printer handle freed per job in finally; no leak or double free; failed jobs still end page/doc.
  • USB (Android): no reconnect inside writeBytes when already connected; failed connect / write now reported as errors; disconnect safe when not connected; pair() is a no-op.
  • Network: socket errors handled (no unhandled isolate crash), dead sockets detected, connect timeout default, flush/close with timeout, always destroyed.
  • Bluetooth: no NoSuchMethodError in connect error handling, "already connected" retried once (no infinite loop), iOS write awaited.
  • Android: onActivityResult no longer swallows other plugins' results; duplicate listeners removed.
  • New LabelJob.build(image, language:, dpi:, compression:): one label image to a TSPL, ESC/POS or CPCL job at 203 or 300 dpi. Compression skips blank rows (ESC/POS feeds over them, CPCL sends binary CG instead of hex EG), so jobs are smaller and faster over Bluetooth; works on any printer of that language.
  • LabelJob: media (gap / black mark / continuous) and topOffsetMm. ESC/POS label jobs now end with GS FF (feed to next label start) -- verified on an LD0801 / DeTong DP27 raster label printer, which speaks ESC/POS raster only (no TSPL, no text font). LabelCommands: TSPL calibrate (GAPDETECT/BLINEDETECT), self test, text-only test.
  • LabelLanguage.detong: DeTong DP27 / LD0801 own raster protocol (as sent by the maker's Windows driver) -- row run-length + repeat, ~2.5x smaller than ESC/POS raster; 1F 27 darkness.
  • ESC/POS label jobs are sent as one raster block (blank rows above/below trimmed) instead of 128-row bands.
  • Example: Label settings card (language, DPI, compression, size, gap) and a Label print button on the USB, Bluetooth and network screens.
  • Requires drago_blue_printer ^1.0.4 and drago_usb_printer ^0.1.7.
