Methods

addBase64Image(String base64, {PosAlign align = PosAlign.center}) → Future<void>

addBytes(Uint8List byte) → void

addCut() → void

addDoubleText(String leftValue, String rightValue, {int leftWidth = 6, int rightWidth = 6}) → void

addFeed({int lines = 1}) → void

addFullHorizontalLine({String ch = '-'}) → void

addImage(RasterImage image, {PosAlign align = PosAlign.center}) → Future<void>

addQrCode(String data, {QRSize size = QRSize.size6}) → void

addQrCodeAsImage(String data, {int size = 280, bool raster = true}) → Future<void>

QR als Bild. raster true → GS v 0 (imageRaster), false → ESC * (image). Welcher Befehl funktioniert, hängt vom Drucker ab — daher umschaltbar.

addReverseFeed({int lines = 1}) → void

addText(String text, {PosStyles styles = const PosStyles()}) → void

addUint8ListImage(Uint8List image, {PosAlign align = PosAlign.center}) → Future<void>

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reset() → void

setBelegLayout(BelegLayout layout, {bool cut = true}) → void

Druckt ein Beleg-Zeilenmodell des Backends (KasseneckReceipt.layout) über das Zeichenraster (BelegRaster, Zwilling von renderReceiptGrid im JS-Paket): jede Rasterzeile geht als fertige, exakt N Zeichen breite Textzeile raus (58 mm = 32, 80 mm = 48) — keine eigene Spaltenrechnung, dieselben Zeilen wie Browser-Kasse, Labor und Beleg-PDF. Bevorzugt gegenüber setKeckReceipt, sobald ein Layout vorliegt.

setKeckReceipt(KasseneckReceipt receipt, {QrPrintMode qrMode = QrPrintMode.imageRaster}) → Future

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

renderQrMatrix(String data, {int size = 280}) → RasterImage

Rastert die QR-Modul-Matrix von data in ein reines schwarz/weiss-Bild (RGBA, Werte nur 0 oder 255 — kein Anti-Aliasing, keine Graustufen).
