在Java 7中打印到打印机 [英] In Java 7 Print to a Printer

本文介绍了在Java 7中打印到打印机的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我已经看过每个网站也可以提到我已经在这里待了3个星期



系统是W7 pro cannon mp560打印机

我有一个小应用程序创建一个文本文件我试图读取txt文件并将其打印到打印机。我宁愿从应用程序中读取JFormatedTextFields并将这些

打印到打印机但是如果我无法打印文本文件则后者处于暂停状态

我使用过Visual基本6和HTML5 JQuery，可以从这些打印，但不是java

代码下面是一个带有布局的JFrame上的按钮（null）



< private void =mode =hold>

JPanel pBtmR = new JPanel（）;

pBtmR.setBounds（630,620,300,120 ）;

pBtmR.setLayout（新BoxLayout（pBtmR，BoxLayout.Y_AXIS））;

JButton btnPrint =新JButton（PRINT）;

//btnPrint.setBounds(650,650,70,30）;



//btnPrint.setSize(90,30）;

btnPrint.setBorder（BorderFactory.createMatteBorder（3,3,3,3，Color.blue））;

//btnPrint.setBorder(BorderFactory.createEmptyBorder(10,10,10,10） ）;

//btnPrint.setBackground(Color.blue);



btnPrint.setMaximumSize（new Dimension（70,30））;

btnPrint.setAlignmentX（Component.CENTER_ALIGNMENT）;



btnPrint.addActionListener（new ActionListener（）{

@Override

public void actionPerformed（ActionEvent e）{



final PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet（） ;

attributes.add（DialogTypeSelection.NATIVE）;

PrinterJob printJob = PrinterJob.getPrinterJob（）;

printJob.printDialog（attributes）;





// String defaultPrinter = PrintServiceLookup.lookupDefaultPrintService（）。getName（）;

//系统.out.println（默认打印机：+ defaultPrinter）;



PrintService服务= PrintServiceLookup.lookupDefaultPrintService（）;



FileInputStream in = null;

try {

in = new FileInputStream（new file（C：/ Users / Dwight Norris / workspace / ZPzProject / PizzaOrder） 。文本）） ;

//System.out.println（in）;

} catch（FileNotFoundException e2）{

// TODO自动生成的捕获块

e2.printStackTrace（）;

}



PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet（）;

pras.add（新副本（1））;



DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;

Doc doc = new SimpleDoc（in，flavor，null）;



DocPrintJob job = service.createPrintJob（）;

//系统。 out.println（job）;

PrintJobWatcher pjw = new PrintJobWatcher（job）;



try {

job.print（doc，pras）;

} catch（PrintException e1）{

// TODO自动生成的捕获块

e1。 printStackTrace（）;

}

pjw.waitForDone（）;



试试{

in.close（）;

} catch（IOException e1）{

// TODO自动生成的catch块

e1.printStackTrace（）;

}



//发送FF以弹出页面

InputStream ff = new ByteArrayInputStream（\ f.getBytes（））;

Doc docff = new SimpleDoc（ff，flavor，null）;

DocPrintJob jobff = service.createPrintJob（）;

pjw = new PrintJobWatcher（jobff）;

try {

jobff.print（docff，null） ;

System.out.println（我打印+作业）;

} catch（PrintException e1）{

// TODO自动生成的捕获块

e1.printStackTrace（）;

}

pjw.waitForDone（）;

}

class PrintJobWatcher {

boolean done = false;





PrintJobWatcher （DocPrintJob工作）{

job.addPrintJobListener（new PrintJobAdapter（）{

public void printJobCanceled（PrintJobEvent pje）{

allDone（）;

}

public void printJobCompleted（PrintJ obEvent pje）{

allDone（）;

}

public void printJobFailed（PrintJobEvent pje）{

allDone （）;

}

public void printJobNoMoreEvents（PrintJobEvent pje）{

allDone（）;

}

void allDone（）{

synchronized（PrintJobWatcher.this）{

done = true;

System.out .println（打印完成......）;

PrintJobWatcher.this.notify（）;

}

}

}）;

}

public synchronized void waitForDone（）{

try {

while （！完成）{

wait（）;

}

} catch（InterruptedException e）{

}

}

}

}）;

//打印结束======== ========================>

解决方案

我看过每个网站从也可以提到我已经在这3个星期



系统是W7 pro cannon mp560打印机

我有一个小应用程序创建一个文本文件我试图读取txt文件并将其打印到打印机。我宁愿从应用程序中读取J格式化文本字段并将这些

打印到打印机，但如果我无法打印文本文件，后者将被暂停

我有使用Visual Basic 6和HTML5 JQuery，可以从这些打印但不是java



我不知道问题在哪里抱歉！

很抱歉代码问题，现在我们有一个看似解决方案的回复

你看过 http://docs.oracle.com/ javase / tutorial / 2d / printing / [ ^ ]或 http://docs.oracle.com/javase/tutorial/uiswing /misc/printtext.html [ ^ ] 

I have seen every web-site from too may places to mention I have been at this for 3 weeks



System is W7 pro cannon mp560 printer 

I have a small app that creates a text file I am trying to read the txt file and print it to the printer. I would rather read the JFormatedTextFields from the app and print these

to the printer but if I can not print a text file the latter is on hold

I have worked with Visual Basic 6 and HTML5 JQuery and can print from these but NOT java

code below is behind a button on a JFrame with Layout(null)
