Printing to Local Printer

[Steve Dyke]

I have been successful with creating a class to print ZPLII string to the LPT1 port for printing labels to a Zebra printer. However, it only works when I run it on a local web app host. It fails when I deploy it to the production we app host.

My code:

 
public String errorString;

public LabelPrinter(String mono, String partno, String ssid) {
try{
PrintService psZebra = null;
String sPrinterName = null;

PrintService service = PrintServiceLookup.lookupDefaultPrintService();

psZebra = service;
 
String s = "^XA\n^FO5,10^AE^FD" + mono + "^FS^FO5,40^AE^FD" + partno + "^FS^^FO5,70^AE^FD" + ssid + "^FS^\n^XZ";
byte[] by = s.getBytes();
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();

DocPrintJob job = psZebra.createPrintJob();

 
Doc doc = new SimpleDoc(by, flavor, null);

job.print(doc, null);


} catch (PrintException e) {
e.printStackTrace();
} 

}
