Print HTML File Without Showing on Screen

Question

Hi Everyone
Is there a way to print a file (in particular, an html file) from a java app without actually displaying the file on the screen.
ie. print from command line.
I am creating an html file from within java app and would like to print it in one step.
Any help would be greatly appreciated.
Thanks
Kelly

Hi,
Heres some code from an app I wrote that prints out text. I've stripped out little sensitive bits.
// Procedure to perform when print button is pressed
   void printButton_actionPerformed(ActionEvent e){
     int x, y, pageNo = 1, maxPageHeight, textHeight = 0;
     Date today = new Date();
     String tempLine = new String("");
     String tempString = new String();
     Graphics pg;
// Create date and time formats
     SimpleDateFormat dateFormatter = new SimpleDateFormat("dd/MM/yy");
     SimpleDateFormat timeFormatter = new SimpleDateFormat("HH:mm:ss");
// Create date and time strings
     currentDate = dateFormatter.format(today);
     currentTime = timeFormatter.format(today);
// Turn off double buffering
     RepaintManager.currentManager(this).setDoubleBufferingEnabled(false);
// Get a print job
     PrintJob printjob = getToolkit().getPrintJob(this, "<printjob name>", null);
     if (printjob != null) {
       maxPageHeight = printjob.getPageDimension().height-(rowHeight*2);
       pg = printjob.getGraphics();
       if (pg != null) {
         pg.setColor(Color.black);
         pg.setFont(new Font("Courier", 0, 10));
// Print header
         textHeight = topOfPage;
         pg.drawString("Report      Date " + currentDate +
                       "      Time " + currentTime + "  Page " + pageNo,
                       30, textHeight);
         textHeight += rowHeight;
         pg.drawString("File: " + dataFile , 30, textHeight);
// Print errors
         textHeight += rowHeight*2;
         pg.drawString("Errors", 30, textHeight);
         textHeight += rowHeight;
         pg.drawString("------", 30, textHeight);
         textHeight += rowHeight;
         pg.drawString("col1         col2 col3                 Value        Reason",
                        30, textHeight);
         textHeight += rowHeight;
         pg.drawString("------------ ---- -------------------- ------------ --------------------",
                        30, textHeight);
         if(errorData != null){
           for(x = 0; x < errorData.length; x++){
             textHeight += rowHeight;
             if(textHeight > maxPageHeight){
               pg = nextPage(pg, printjob, ++pageNo);
               textHeight = topOfPage + rowHeight*2;
             tempLine = "";
             for(y=0; y<columnLengths.length; y++){
               tempString = errorData[x][y] != null ?
                            roundLength(errorData[x][y].toString(), columnLengths[y])
                            : roundLength(" ", columnLengths[y]);
               tempLine += tempString + " ";
             pg.drawString(tempLine, 30, textHeight);
         pg.dispose(); // flush page
       printjob.end();
   }Hope that helps.
Rob.
