react-native-epson-escposprinter

A React Native wrapper of the
Epson ePOS SDK,
supporting the
New Architecture
and classic builds.

The current version embeds these SDKs:

1. Epson ePOS SDK for Android Version 2.32.0
1. Epson ePOS SDK for iOS Version 2.32.0

Usage

Most of the methods are a simple wrapper of the native SDK. For a complete list
of methods and their details, you may refer to the API reference file found in
the Epson SDK archive.

``tsx
import {
connect,
discoverPrinters,
getPrinterSeriesFromDeviceName,
PrinterLocale,
} from "react-native-epson-escposprinter";
import { ok } from "assert";

for await (const info of discoverPrinters()) {
const series = getPrinterSeriesFromDeviceName(info.deviceName);
ok(series, Unknown device ${info.deviceName});

const printer = await connect(series, PrinterLocale.MODEL_ANK, info.target);

await printer.transaction(async () => {
await printer.addText("ABC");
await printer.sendData();
await printer.clearCommandBuffer();
});

await printer.disconnect();
}
`
