Print

printImage sends a base64 image (MIME type removed) to a Brother printer. Call this after Installation. Discover a printer with Search and register Events for print results before printing.

Prepare a real image yourself (for example encode a PNG/JPEG from your app and strip any data:...;base64, prefix). Use port and channelInfo from the BRLMChannelResult you retained from onPrinterAvailable. Pick a modelName / labelName that matches your device and the supported models table.

import {
  BrotherPrint,
  BRLMPrinterLabelName,
  BRLMPrinterModelName,
} from '@rdlabo/capacitor-brotherprint';
import type { BRLMChannelResult, BRLMPrintOptions } from '@rdlabo/capacitor-brotherprint';

const printImage = async (printer: BRLMChannelResult, encodedImage: string) => {
  const options: BRLMPrintOptions = {
    modelName: BRLMPrinterModelName.QL_820NWB,
    labelName: BRLMPrinterLabelName.RollW62,
    encodedImage,
    numberOfCopies: 1,
    autoCut: true,
    port: printer.port,
    channelInfo: printer.channelInfo,
  };

  await BrotherPrint.printImage(options);
};
