Java Print

[Meet Gaurav]

Hi,

I have a Java bean which prints a text files which is generated by oracle. Am using Jeditorpane for printing, Curently this is printingall types of files like html, text and rtf files. But this java bean is not able to identify the end of page.

its simply printing a small square box in place of end of page character. Could some one please help me to resolve the issue.

  


class RTFPrinter implements Printable
{

 private int currentPage;
 private JEditorPane jeditorPane;
 private double pageEndY;
 private double pageStartY;
 private boolean scaleWidthToFit;
 private PageFormat pFormat;
 private PrinterJob pJob;
 
	 
 public void loadProperties()
 {
   currentPage = -1;
   pageEndY = 0.0D;
   pageStartY = 0.0D;
   scaleWidthToFit = true;	 
   pFormat = new PageFormat();
   pJob = PrinterJob.getPrinterJob();
 }

 // This will print text files with all Extensions, rtf and html.
 protected void print_txt_html(String filePath) throws Exception
 {
    if(filePath != null)
    {	 
	  try 
	  {
		loadProperties();
	    jeditorPane = new JEditorPane();
	    jeditorPane.setEditable(false);
	  	URL urlObj = null;
		  urlObj = new File(filePath).toURI().toURL();
	    if (urlObj != null)
	    {
	      jeditorPane.setPage(urlObj);
	    }
	    jeditorPane.setContentType(jeditorPane.getContentType());
	    printDialog();
	  }
	  catch (Exception e)
	  {
	    throw e;
	  }
	}
 }  // End of print_txt(String filePath)

[Meet Gaurav]

someone please help me to resolve this issue

Too difficult a question for beginners. Moving.

Hi there,

This has probably something to do with Character Encoding. What character encoding are you using? Is it consistent throughout your code?

[Meet Gaurav]

Martin,

Thanks for the reply. Am new to java, I submitted the full code. Please help me.

[Martijn Verburg]

OK, firstly, you need to look up encoding, here are some articles to help:

here
and
here

Then start looking at the Javadocs for some of the methods that you are using to display and translate text, can you see versions of that same method that take an encoding? You'll want to experiment with those...
