Facing issues while printing on Dot Matrix Printer - swing

Question

I am developing a desktop application in java swing; in which I need to take a bill print on dot matrix printer, the print will be having name, address and table which will be having item, qty, price…etc, which should be printed as per their x, y positions on paper, font stored in database .
But in print there is issue of overlapping/attaching letters if I use the following code:
class BillPrint implements ActionListener, Printable
{
PrintMngt PM=new PrintMngt();
public int print(Graphics gx, PageFormat pf, int page) throws PrinterException {
if (page>0){return NO_SUCH_PAGE;}
Graphics2D g = (Graphics2D)gx; //Cast to Graphics2D object
g.translate(pf.getImageableX(), pf.getImageableY());
Vector<Vector<Object>> data =PM.getvarientDetail(printID);
for (int i = 0; i <data.size(); i++) {
if(data.get(i).get(3).toString().equalsIgnoreCase("DYNAMIC"))
{
String bill_no=textField_Trans.getText();
int TblH,TblL;
Vector<String> Tbl_HL=PM.getTblHieghtNoLline(printID);
//PRINT_ID0, QUERY_STATIC1, OBJECT_NAME2, QUERY_TYPE3, X4, Y5, WIDTH6,
//ALIGN7, FONT8, F_SIZE9, F_STYLE10, SECTION11, LOOPES_NO12, OBJ_FORMAT13, VARIANT_ID14
TblH=Integer.parseInt(Tbl_HL.get(0).toString());
TblL=Integer.parseInt(Tbl_HL.get(1).toString());
int x=Integer.parseInt(data.get(i).get(4).toString());
int y=Integer.parseInt(data.get(i).get(5).toString());
String fName=data.get(i).get(8).toString();
int fSize=Integer.parseInt(data.get(i).get(9).toString());
String fStyle=data.get(i).get(10).toString();
Font font=null;
if(fStyle.equalsIgnoreCase("Plain"))
{
font = new Font(fName,Font.PLAIN, fSize);
}
else if(fStyle.equalsIgnoreCase("Bold"))
{
font = new Font(fName,Font.BOLD, fSize);
}
else if(fStyle.equalsIgnoreCase("Italic"))
{
font = new Font(fName,Font.ITALIC, fSize);
}
else if(fStyle.equalsIgnoreCase("Bold Italic"))
{
font = new Font(fName,Font.BOLD+ Font.ITALIC, fSize);
}
System.out.println("Myqry"+data.get(i).get(1).toString());
Vector<String> Query_Static=PM.getQuery_Static(data.get(i).get(1).toString(),bill_no);
for (int j = NoOfProd; j < Query_Static.size(); j++) {
g.drawString(Query_Static.get(j).toString(),x,y);
y=y+TblH/TblL;
g.setFont(font);
}
}
}
return PAGE_EXISTS; //Page exists (offsets start at zero!)
}
public void actionPerformed(ActionEvent e) {
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(this);
boolean ok = job.printDialog();
if (ok) {
try {
int ProductCnt= PM.getNoProduct(textField_Trans.getText().toString());//no. of products under given billno
int TableLine=PM.getTblNoLline(printID);//no. of lines to print
System.out.println("No of TableLines="+TableLine);
System.out.println("No of Product="+ProductCnt);
for (int i = 0; i <(TableLine/ProductCnt); i++)
{
job.print();
NoOfProd=NoOfProd+TableLine;
}
NoOfProd=0;
} catch (PrinterException ex) {
ex.printStackTrace();
}
}
}//end actionPerformed
}//end BillPrint
I have also tried with writing data to .txt file and then printing it. Here output is proper i.e letters are not overlapping , but here in this method I m not able to give proper positions for my data. Following method I used for this:
private void printData(){
File output = new File("E:\\PrintFile1.txt");
output.setWritable(true);
String billNo="B1000", patient = "ABC";
try
{
BufferedWriter out = new BufferedWriter(new FileWriter(output));
out.write(billNo + "\n");
out.write(patient + "\n" );
out.write("\n");
out.write("\n");
out.close();
}
catch (java.io.IOException e)
{
System.out.println("Failed to write Output");
}
FileInputStream textStream = null;
try
{
textStream = new FileInputStream("E:\\PrintFile1.txt");
}
catch (java.io.FileNotFoundException e)
{
System.out.println("Error trying to find the print file.");
}
DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
Doc mydoc = new SimpleDoc(textStream, flavor, null);
PrintService printer = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob printJob = printer.createPrintJob();
try
{
printJob.print(mydoc, null);
}
catch (javax.print.PrintException e)
{
JOptionPane.showMessageDialog(this, "Error occured while attempting to print.", "Error!", JOptionPane.ERROR_MESSAGE);
}
}

Basically for the issue in the letters i just add one space for each character in the string
import java.awt.Font;
import java.awt.FontMetrics;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import java.awt.print.PrinterException;
public class Print implements Printable {
/* Just add one space for all charaters */
String numero = "Numero Nro :";
String numeroreplace = numero.replaceAll(".(?=.)", "$0 ");
public Print() {
super();
}
/* The font for you string */
public int print(Graphics g,PageFormat pf, int page) throws PrinterException{
Font textFont = new Font(Font.SANS_SERIF,Font.PLAIN,8);
/* To set the position, you can use for or while if u need it. */
g.setFont(textFont);
g.drawString(numeroreplace,350,150);
}
}
Finally you need to copy all this code just add one space for all characters in code.
Note : you must be call from yor main program.
