Print text File to specific printer in java

Question

I have a text file, and I need to print it to a specific network printer. I know the name of the printer.

Until now I have made a Printable class to print my file (t

Answer 1

JTextComponent#print should do the trick:

JTextPane jtp = new JTextPane();
jtp.setBackground(Color.white);
jtp.setText("text to print");
boolean show = true;
try {
    jtp.print(null, null, show, null, null, show);
} catch (java.awt.print.PrinterException ex) {
    ex.printStackTrace();
}

in this manner you can quickly print out even nice formatted text - just create a StyledDocument and attach it to JTextPane before printing.

I'm not sure if this solves your problem but I use the following to print a text file

FileInputStream textStream;
textStream = new FileInputStream(FILE_NAME);

DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
Doc mydoc = new SimpleDoc(textStream, flavor, null);

   PrintService[] services = PrintServiceLookup.lookupPrintServices(
                flavor, aset);
   PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();

   if(services.length == 0) {
       if(defaultService == null) {
             //no printer found

       } else {
            //print using default
            DocPrintJob job = defaultService.createPrintJob();
            job.print(mydoc, aset);

       }

    } else {

       //built in UI for printing you may not use this
       PrintService service = ServiceUI.printDialog(null, 200, 200, services, defaultService, flavor, aset);


        if (service != null)
        {
           DocPrintJob job = service.createPrintJob();
           job.print(mydoc, aset);
        }

    }

You may not need the ServiceUI, but I think you could use PrintService[] services to get a list of printers available for printing. And using an input stream and the Doc class you can print a file to a printer.
