Events
Listen for discovered printers and print results. Register listeners before Search and Print so the first events are not missed.
import type { PluginListenerHandle } from '@capacitor/core';
import { BrotherPrint, BrotherPrintEventsEnum } from '@rdlabo/capacitor-brotherprint';
const handles: PluginListenerHandle[] = [];
const registerPrintListeners = async () => {
handles.push(
await BrotherPrint.addListener(BrotherPrintEventsEnum.onPrinterAvailable, (printer) => {
console.log('printer', printer.channelInfo);
}),
);
handles.push(
await BrotherPrint.addListener(BrotherPrintEventsEnum.onPrint, () => {
console.log('onPrint');
}),
);
handles.push(
await BrotherPrint.addListener(BrotherPrintEventsEnum.onPrintFailedCommunication, (info) => {
console.log('onPrintFailedCommunication', info);
}),
);
handles.push(
await BrotherPrint.addListener(BrotherPrintEventsEnum.onPrintError, (info) => {
console.log('onPrintError', info);
}),
);
};
const removePrintListeners = async () => {
await Promise.all(handles.map((handle) => handle.remove()));
};
