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.
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) {
}
}
}
}
