Q1: 如何通过JAVA代码调用网络打印机使其打印接收到的文件

用java实现本地打印：java.awt中提供了一些打印的API,要实现打印，首先要获得打印对象，然后继承Printable实现接口方法print，以便打印机进行打印，最后用用Graphics2D直接输出直接输出。下面代码实现了简单的打印功能：

Q2: Java如何调用TSC打印机进行打印详解

给你介绍一种后台打印方法：

使用javax中的PrintServiceLookup类进行打印，可以直接调用默认的打印机，也可以使用下列的方法进行筛选打印:

PrintServiceLookup.lookupMultiDocPrintServices(flavors, attributes);

可执行代码如下：

Q3: 求用java代码控制斑马条码打印机打印二维码商标的例子程序

可以参考下.自己写java打印机代码的一个例子

import java.awt.Graphics;

import java.awt.Graphics2D;

import java.awt.Image;

import java.awt.print.PageFormat;

import java.awt.print.Paper;

import java.awt.print.Printable;

import java.awt.print.PrinterException;

import java.awt.print.PrinterJob;

import java.util.Queue;

import com.google.zxing.WriterException;

public class QrPrint implements Printable {

public void print() throws PrinterException {

PrinterJob pj = PrinterJob.getPrinterJob();

PageFormat pf = pj.defaultPage();

Paper paper = new Paper();

double margin = 0.1; // half inch

paper.setImageableArea(margin, margin, paper.getWidth() - margin * 2,paper.getHeight() - margin * 2);

pf.setPaper(paper);

pj.setPrintable(this, pf);

pj.print();

}

public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {

if ("判断如果打印完java打印机代码了就退出") {

return Printable.NO_SUCH_PAGE;

}

try {

Image eanImage = generateEANBufferedImage(content,120,20);

Graphics2D g2 = (Graphics2D) graphics;

g2.translate(pageFormat.getImageableX(), pageFormat.getImageableY()); //设置可成像java打印机代码的X和Y轴java打印机代码的距离

g2.drawImage(eanImage, 0, 80, null); //设置打印的边距

g2.drawString("字符串:",130,20);

} catch (WriterException e) {

e.printStackTrace();

return Printable.NO_SUCH_PAGE;

}

return Printable.PAGE_EXISTS;

}

private BufferedImage generateBufferedImage(String content,int width,int height) throws WriterException {

HashtableEncodeHintType,String hints = new HashtableEncodeHintType,String();

hints.put(EncodeHintType.CHARACTER_SET, "utf-8");

BitMatrix bitMatrix = new MultiFormatWriter().encode(content, BarcodeFormat.EAN_13, width, height, hints);

return MatrixToImageWriter.toBufferedImage(bitMatrix);

}

Q4: 怎么用java调用默认打印机打印文档？

java实现调用默认打印机打印文档（以D盘zhidao.txt文档为例）java打印机代码，代码如下java打印机代码：

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import javax.print.Doc;

import javax.print.DocFlavor;

import javax.print.DocPrintJob;

import javax.print.PrintException;

import javax.print.PrintService;

import javax.print.PrintServiceLookup;

import javax.print.ServiceUI;

import javax.print.SimpleDoc;

import javax.print.attribute.DocAttributeSet;

import javax.print.attribute.HashDocAttributeSet;

import javax.print.attribute.HashPrintRequestAttributeSet;

import javax.print.attribute.PrintRequestAttributeSet;

/**

public class PrintDemoII {

public static void main(String[] args) {

DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;

PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();

PrintService []pservices = PrintServiceLookup.lookupPrintServices(flavor, aset);

PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();

PrintService service = ServiceUI.printDialog(null, 200, 200, pservices,

defaultService, flavor, aset);

if(service != null){

try {

DocPrintJob pj =service.createPrintJob();

FileInputStream fis = new FileInputStream("D:"+ File.separator +"zhidao.txt");//打印D盘zhidao.txt文档。

DocAttributeSet das = new HashDocAttributeSet();

Doc doc = new SimpleDoc(fis, flavor, das);

pj.print(doc, aset);

} catch (FileNotFoundException fe) {

fe.printStackTrace();

} catch (PrintException e) {

e.printStackTrace();

}

}else {

System.out.println("打印失败");

}

Q5: java怎么实现打印机打印

接口 PrintService 是 DocPrintJob 的工厂。PrintService 描述了打印机的功能，并可查询它来了解打印机支持的属性
