java 调用打印机程序

public static void main(String[] args) {

JFileChooser fileChooser = new JFileChooser(); //创建打印作业

int state = fileChooser.showOpenDialog(null);

if(state == fileChooser.APPROVE_OPTION){

File file = new File("D:/zkyzl.txt"); //获取选择的文件

//构建打印请求属性集

HashPrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();

//设置打印格式，因为未确定类型，所以选择autosense

DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;

//查找所有的可用的打印服务

PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);

//定位默认的打印服务

PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();

//显示打印对话框

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

defaultService, flavor, pras);

if(service != null){

try {

DocPrintJob job = service.createPrintJob(); //创建打印作业

FileInputStream fis = new FileInputStream(file); //构造待打印的文件流

DocAttributeSet das = new HashDocAttributeSet();

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

job.print(doc, pras);

} catch (Exception e) {

e.printStackTrace();

}

}

}
