Rendering Barcode to Printer in Java

Introduction

Creating and rendering barcodes in Java can be a breeze with Aspose.BarCode. In this tutorial, we’ll guide you through the process of rendering a barcode to a printer using Aspose.BarCode for Java. Whether you’re a seasoned developer or just starting, this step-by-step guide will help you integrate barcode generation seamlessly into your Java applications.

Prerequisites

Before we dive into the tutorial, make sure you have the following prerequisites in place:

  • Java Development Kit (JDK) installed on your machine.
  • Aspose.BarCode for Java library. You can download it from here.
  • An integrated development environment (IDE) such as Eclipse or IntelliJ.

Import Packages

In your Java project, import the necessary packages to leverage Aspose.BarCode functionalities. Add the following import statements to your Java class:

import java.awt.Dimension;
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import com.aspose.barcode.generation.BarcodeGenerator;

Step 1: Create Frame Instance

Frame f = new Frame();
f.setSize(300, 300);

Create a frame instance, set its size, and prepare it to display the barcode.

Step 2: Create Barcode Instance

BarcodeGenerator bb = new BarcodeGenerator(com.aspose.barcode.EncodeTypes.CODE_128, "1234567");

Initialize a BarcodeGenerator instance with the desired barcode type and data.

Step 3: Generate Barcode Image

BufferedImage bimg = (BufferedImage) bb.generateBarCodeImage();

Generate the barcode image using the BarcodeGenerator instance.

Step 4: Extract RGB Information

int w = bimg.getWidth();
int h = bimg.getHeight();
int[] rgb = new int[w * h];
bimg.getRGB(0, 0, w, h, rgb, 0, w);

if (rgb.length > 0) {
    System.out.println("RGB OK.");
}

Extract RGB information from the generated barcode image.

Step 5: Display Barcode on Frame

g.drawImage(bimg, 0, 0, this);

Display the barcode on the frame using the Graphics class.

Step 6: Set Frame Visibility

f.setVisible(true);

Make the frame visible, showcasing the rendered barcode.
