How send a html file direclty to the printer in java - swing

Question

I'm using this to send a htlm file direclty to printer and it says invalid flavour which means that the printer does not support the formats. Any one have an idea to do this..
/**
* #param args
*/
public static void main(String[] args) {
// Input the file
FileInputStream textStream = null;
try {
textStream = new FileInputStream("./some.html");
} catch (FileNotFoundException ffne) {
}
if (textStream == null) {
return;
}
// Set the document type
DocFlavor myFormat = DocFlavor.INPUT_STREAM.TEXT_HTML_HOST;
// Create a Doc
Doc myDoc = new SimpleDoc(textStream, myFormat , null);
// Build a set of attributes
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(new Copies(1));
//aset.add(MediaSize.NA.LEGAL);
aset.add(Sides.ONE_SIDED);
// discover the printers that can print the format according to the
// instructions in the attribute set
PrintService services = PrintServiceLookup.lookupDefaultPrintService();
//PrintServiceLookup.lookupPrintServices(myFormat, aset);
// Create a print job from one of the print services
//System.out.println("====5======="+service.get);
//if (services.length > 0) {
for (int i = 0; i < services.getSupportedDocFlavors().length; i++) {
System.out.println("====getSupportedDocFlavors======="+services.getSupportedDocFlavors()[i]);
}
DocPrintJob job = services.createPrintJob();
try {
job.print(myDoc, aset);
} catch (PrintException pe) {
System.out.println("====PrintException======="+pe);
}
//}
}
It says
sun.print.PrintJobFlavorException: invalid flavor

Answer 1

You are trying to force printer to handle (render) HTML document onto the paper. It will never work that way. And ofcourse the flavor you are sending is not supported.
First of all you need to render HTML into some graphical representation and then send it to printer. There are no good cross-platform tools for Java that could render modern HTML pages. But there is one in JavaFX and i guess you could use it to handle the task.
About printing the final image you can read here:
http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/Swing-Tutorial-Printing.html
or see the code here:
http://www.java2s.com/Code/Java/2D-Graphics-GUI/PrintanImagetoprintdirectly.htm
or just find any other resource - there are a lot about printing.
