        if(printservice.length!=1){
            System.out.println("Printer not found");
        }
        PrintService pservice = printservice[0];
        DocPrintJob job = pservice.createPrintJob();
        DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
        Doc doc = new SimpleDoc(open,flavor,null);
        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
        try {

Java is not my specialty, but I know this problem.
You want to print this escape command to the printer as raw data.

You need to search internet with :
- Java print raw data
- Java print escape command

The question was asked in many forum, you hace yo see which answer will fit your needs.

I have found an example that I know is working, because I don't use Java.
But I am familiar with raw printing with xHarbour/Harbour/Clipper/FoxPro/dBase langauges going back to DOS age.

Sorry...
I didnot visited this page for long time.

public void cashdrawerOpen() {

byte[] open = {27, 112, 48, 55, 121};
// byte[] cutter = {29, 86,49};
String printer = PrinterName;
PrintServiceAttributeSet printserviceattributeset = new HashPrintServiceAttributeSet();
printserviceattributeset.add(new PrinterName(printer,null));
PrintService[] printservice = PrintServiceLookup.lookupPrintServices(null, printserviceattributeset);
if(printservice.length!=1){
System.out.println("Printer not found");
}
PrintService pservice = printservice[0];
DocPrintJob job = pservice.createPrintJob();
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
Doc doc = new SimpleDoc(open,flavor,null);
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
try {
job.print(doc, aset);
} catch (PrintException ex) {
System.out.println(ex.getMessage());
