Limitations

When using Android device, an image specified by URL is sometimes printed in a low resolution

In Android, when an image file size is large, and its URL is specified as the source of the ImageParameter which is the argument of the actionPrintImage method, the image may be printed in low resolution.

This can be solved by either of the following methods:

• Reduce a file size of an image by lowering the resolution beforehand.
• Download an image in the app and specify the image file directly as the source.

Examples

Discover devices

manager: StarDeviceDiscoveryManager;

async discover(): Promise<void> {
    try {
        // Specify your printer interface types.
        manager = await StarDeviceDiscoveryManagerFactory.create([
            InterfaceType.Lan,
            InterfaceType.Bluetooth,
            InterfaceType.BluetoothLE,
            InterfaceType.Usb
        ]);

        // Set discovery time. (option)
        manager.discoveryTime = 10000;

        // Callback for printer found.
        manager.onPrinterFound = (printer: StarPrinter) => {
            console.log(printer);
        };

        // Callback for discovery finished. (option)
        manager.onDiscoveryFinished = () => {
            console.log(`Discovery finished.`);
        };

        // Start discovery.
        await manager.startDiscovery();

        // Stop discovery.
        // await manager.stopDiscovery()
    }
    catch(error) {
        // Error.
        console.log(error);
    }
}

Print

async print(): Promise<void> {
    // Specify your printer connection settings.
    var settings = new StarConnectionSettings();

    var printer = new StarPrinter(settings);

    try {
        // Connect to the printer.
        await printer.open();

        // create printing data. (Please refer to 'Create Printing data')
        var builder = new StarXpandCommand.StarXpandCommandBuilder();
        // ...
        var commands = await builder.getCommands();

        // Print.
        await printer.print(commands);
    }
    catch(error) {
        // Error.
        console.log(error);
    }
