需要的jar和dll下載路徑http://download.csdn.net/detail/daixinmei/7962251

dll要放在windows/system32下，或者jdk安裝目錄的bin下

怎使用java調用預設印表機列印文檔？

PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
//設定列印格式，因為未確定檔案類型，這裡選擇AUTOSENSE
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
//尋找所有的可用列印服務
PrintService printService[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
//定位預設的列印服務
PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
//顯示列印對話方塊
PrintService service = ServiceUI.printDialog(null, 200, 200, printService, defaultService, flavor, pras);
if (service != null) {
try {
DocPrintJob job = service.createPrintJob(); //建立列印工作
FileInputStream fis = new FileInputStream(file); //構造待列印的檔案流
DocAttributeSet das = new HashDocAttributeSet();
Doc doc = new SimpleDoc(fis, flavor, das); //建立列印檔案格式
job.print(doc, pras); //進行檔案的列印
}catch(Exception e) {
e.printStackTrace();
}
}
