Error when printing jasper report with Epson lx-300+ii printer in windows 7 from my java application

[chalithalawanga]

I created a java application and it is running on windows 7 finely. I created Jasper reports for that software when I try to print a report from Epson lx-300+ii printer letters are printing with out spaces and it is difficult to read.But when I print another document from another software like Microsoft word it prints fine. 

Picture of the report:

Code that I used:

 

public void generateReport() throws PrinterException {

 

try {  

String sourceFileName = "src/POS_bill/esFourReport.jasper";

String printFileName = null;

DataBeanFactory2 DataBean = new DataBeanFactory2();

JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(DataBean.generateCollection());

Map parameters = new HashMap();

printFileName = JasperFillManager.fillReportToFile(

         sourceFileName,

         parameters,

         beanColDataSource);

 

if (printFileName != null){

          JasperPrintManager.printReport(printFileName, false);

          }

} catch (Exception e) {

    JOptionPane.showMessageDialog(null,e);

} 

}

 

someone can help me?

thank you!
