Java实现TSC-244条码打印机驱动与JPEG图片编码

完成此功能的时间 ：3个礼拜

1. 本功能主要实现的是料站的打印成条形后，可以扫描出相应的料站 （打印机的型号是：TSC-244 ）
需要用到的JAR包：avalon-framework-4.2.0.jar，barcode4j.jar 

实现的思路：

1.先在本地生成可以扫描的条形码图片：

 具体代码：如下

package com.songjia.commons.utils.print;

import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.FileOutputStream;

import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGEncodeParam;
import com.sun.image.codec.jpeg.JPEGImageEncoder;

public class JPEGImageTest {
public static void main(String[] args) throws Exception {
// new JPEGImageTest("C:\\JPEGImageTest.jpeg","AF-hh");
JPEGImageTest aa = new JPEGImageTest();
aa.getJPEGImageTest("C:\\JPEGImageTest.jpeg", "AF-h99");
}

public void getJPEGImageTest(String filename, String code) throws Exception {
File file = new File(filename);
file.delete();
FileOutputStream output = new FileOutputStream(file);
BarCode barcode = new BarCode();
barcode.code = code;
barcode.barType = BarCode.CODE128;
barcode.setSize(barcode.width, barcode.height);
// 则采用自动适应条码的尺寸
BufferedImage bufferedimage_temp = new BufferedImage(
barcode.getSize().width, barcode.getSize().height,
BufferedImage.TYPE_BYTE_INDEXED);
Graphics2D graphics2d_temp = bufferedimage_temp.createGraphics();
barcode.paint(graphics2d_temp);
barcode.invalidate();
graphics2d_temp.dispose();
// 格式化图片格式为jpeg
BufferedImage bufferedimage = new BufferedImage(
barcode.getSize().width, barcode.getSize().height,
BufferedImage.TYPE_INT_RGB);
Graphics2D graphics2d = bufferedimage.createGraphics();
barcode.paint(graphics2d);
JPEGImageEncoder jpegimageencoder = JPEGCodec.createJPEGEncoder(output);
JPEGEncodeParam jpegencodeparam = jpegimageencoder
.getDefaultJPEGEncodeParam(bufferedimage);
jpegencodeparam.setQuality(1.0F, true);
jpegimageencoder.setJPEGEncodeParam(jpegencodeparam);
jpegimageencoder.encode(bufferedimage, jpegencodeparam);
bufferedimage.flush();
output.close();
