Java Question

what is the best way to print invoice in java

in my desktop application (POS System). I used IText api for generating invoices and printing, but my printer thermal invoice printer don't support .pdf file. only supporting text file and .docx file. i use simple text file printer print whole invoice in long vertical single word line and don't auto cut page. I used .docx file which works good, i got print as i designed. but my program first open document in ms word then give me print. my code is:

try

{


FileOutputStream output = new FileOutputStream(FILE);
XWPFDocument doc = new XWPFDocument();

CTBody body = doc.getDocument().getBody();
if(!body.isSetSectPr()){
body.addNewSectPr();
}

CTSectPr section = body.getSectPr();
if(!section.isSetPgSz()){
section.addNewPgSz();
}
CTPageSz pageSize = section.getPgSz();
pageSize.setOrient(STPageOrientation.PORTRAIT);

int value = 4000+(gui.model.getRowCount()*1000);

pageSize.setW(BigInteger.valueOf(4050));
pageSize.setH(BigInteger.valueOf(value));

CTPageMar pageMar = section.addNewPgMar();
pageMar.setLeft(BigInteger.valueOf(400L));
pageMar.setTop(BigInteger.valueOf(0L));
pageMar.setRight(BigInteger.valueOf(0L));
pageMar.setBottom(BigInteger.valueOf(0L));

XWPFParagraph para = doc.createParagraph();
para.setAlignment(ParagraphAlignment.LEFT);
XWPFRun run = para.createRun();
para.setWordWrap(true);
run.setBold(true);
run.setFontSize(10);
run.setText(" "+address.shopName);
run.addBreak();
run.setText(" "+address.phoneNo);
run.addBreak();
run.setText(" "+address.description);
run.addBreak();
para = doc.createParagraph();
para.setAlignment(ParagraphAlignment.LEFT);
run = para.createRun();
para.setWordWrap(true);
run.setFontSize(10);
run.setText("Invoice No."+invoiceno);
run.addBreak();
run.setText("Type: "+table);
run.addBreak();
run.setText("Customer Name: "+name+" "+tempObj);
run.addBreak();
run.setText("--------------------------------------------------------");
run.addBreak();
run.setText("Product Qty Price Total");
run.addBreak();
run.setText("--------------------------------------------------------");
run.addBreak();

String temp = null;
for(int i = 0 ; i < gui.table.getRowCount(); i++){
temp = gui.table.getValueAt(i, 1).toString();
String quanstr = gui.table.getValueAt(i, 2)+"";
String unitPricestr = gui.table.getValueAt(i, 3)+"";
String totalstr =gui.table.getValueAt(i, 4)+"";

run.setText(temp);run.addBreak();
run.setText(" "+quanstr+" "+unitPricestr+" "+totalstr);
run.addBreak();
}
double subTotal = tableTotalCounter();
run.setText("--------------------------------------------------------");run.addBreak();
run.setText("Discount: "+dis+"%");run.addBreak();
run.setText("Sub total: "+(subTotal - (subTotal*dis/100)));run.addBreak();
run.setText("Cash: "+cash);run.addBreak();
run.setText("Balance: "+(cash-(subTotal - (subTotal*dis/100))));
run.addBreak();
doc.write(output);
output.close();

} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
System.out.println("Exception");
e1.printStackTrace();
}catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("Exception");
}

if(confirmation("Print invoice?","Confirmation")==0){
Desktop desktop = Desktop.getDesktop();
try {

desktop.print(new File(FILE));
} catch (IOException e) {
e.printStackTrace();
}
}


please tell me how to print without getting that file open. and there is any other way to print invoice.

Answer

Format your invoice in a string and pass to the code I have pasted below. Before executing this code print a test page (windows) (Linux) to make sure your printer is configured correctly.

public class GenerateInvoice {

public static void printInvoice(String invoice) {
      try {
          PrintService mPrinter = null;
          Boolean bFoundPrinter = false;

          PrintService[] printServices = PrinterJob.lookupPrintServices();

          for (PrintService printService : printServices) {
              String sPrinterName = printService.getName();
              if (sPrinterName.equals("Black Cobra")) {
                  mPrinter = printService;
                  bFoundPrinter = true;
              }
          }
          String testData = invoice+"\f";
          InputStream is = new ByteArrayInputStream(testData.getBytes());
          DocFlavor flavor =  DocFlavor.INPUT_STREAM.AUTOSENSE   ;

          PrintService service = PrintServiceLookup.lookupDefaultPrintService();
          System.out.println(service);

          DocPrintJob job = service.createPrintJob();
          Doc doc= new SimpleDoc(is, flavor, null);

          PrintJobWatcher pjDone = new PrintJobWatcher(job);

          job.print(doc, null);

          pjDone.waitForDone();

          is.close();
      } catch (PrintException e) {
          e.printStackTrace();
      } catch (IOException e) {
          e.printStackTrace();
      }
  }
  static class PrintJobWatcher {
      boolean done = false;

      PrintJobWatcher(DocPrintJob job) {
          // Add a listener to the print job
          job.addPrintJobListener(new PrintJobAdapter() {
              public void printJobCanceled(PrintJobEvent pje) {
                  allDone();
              }
              public void printJobCompleted(PrintJobEvent pje) {
                  allDone();
              }
              public void printJobFailed(PrintJobEvent pje) {
                  allDone();
              }
              public void printJobNoMoreEvents(PrintJobEvent pje) {
                  allDone();
              }
              void allDone() {
                  synchronized (PrintJobWatcher.this) {
                      done = true;
                      PrintJobWatcher.this.notify();
                  }
              }
          });
      }
      public synchronized void waitForDone() {
          try {
              while (!done) {
                  wait();
              }
          } catch (InterruptedException e) {
          }
      }
  }

}
