Printing a string

I'm looking for a "standard" solution to taking String contents from a textbox, asking the user to select a printer, then outputing the string to that printer.

I've tried the code below and it never finds any printers.  Granted, I have none connected to my system, but two are located in my Windows printers list.

DocFlavor objInputFormat = DocFlavor.STRING.TEXT_PLAIN;
Doc objDoc = new SimpleDoc(strXML, objInputFormat, null);

PrintRequestAttributeSet objAttributeSet = new HashPrintRequestAttributeSet();
objAttributeSet.add(new Copies(1));
objAttributeSet.add(Sides.ONE_SIDED);

this.lblStatus.setText("Looking for valid printers...");

PrintService[] services = PrintServiceLookup.lookupPrintServices(objInputFormat, objAttributeSet);

if (services.length > 0)
{
...
} else {
   System.out.println("No printers found.");
}
