POS Print Companion App

Overview

This Android app is a wrapper for the NyxPrinterClient, an SDK used for printing receipts from Bitcoinzie POS machines. The app does not have a user interface, which fixes the problem of switching between apps while using Deeplink. It uses a deep link approach to receive data and initiate printing commands.

Description

• The app is designed to work without a user interface, addressing the issue of app switching by running in the background.
• It integrates with the NyxPrinterClient SDK, ensuring compatibility and ease of use for printing receipts from Bitcoinze POS machines.
• By utilizing deep links, the app can process print commands directly from URLs, allowing for efficient communication between applications.

Building the App

To build the app, you need to have the Java Development Kit (JDK-17) installed on your computer. Use the following command to compile the app:

./gradlew assembleDebug

usage

// Define the parameters
var username = 'blinkUsername';
var amount = 'TransactionAmount';
var paymentHash = 'UniquePaymentHash';

// Encode the parameters and construct the deep link URL
var deepLinkUrl = `blink-pos-companion://print?username=${encodeURIComponent(username)}&amount=${encodeURIComponent(amount)}&paymentHash=${encodeURIComponent(paymentHash)}`;

// Redirect to the deep link URL to initiate the printing process
window.location.href = deepLinkUrl;
