How can I use java to call the default printer to print documents?

PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet ();
// Set the print format. Because the file type is not determined, select AUTOSENSE.
DocFlavor flavor = DocFlavor. INPUT_STREAM.AUTOSENSE;
// Find all available printing services
PrintService printService [] = PrintServiceLookup. lookupPrintServices (flavor, pras );
// Locate the default Print Service
PrintService defaultService = PrintServiceLookup. lookupdefaprintprintservice ();
// Display the Print dialog box
PrintService service = ServiceUI. printDialog (null, 200,200, printService, defaultService, flavor, pras );
If (service! = Null ){
Try {
DocPrintJob job = service. createPrintJob (); // create a print job
FileInputStream FCM = new FileInputStream (file); // construct the file stream to be printed
DocAttributeSet das = new HashDocAttributeSet ();
Doc doc = new SimpleDoc (FCM, flavor, das); // create a print file format
Job. print (doc, pras); // print the file
} Catch (Exception e ){
E. printStackTrace ();
}
}
 
Printer printing is called by java programs.
