Printing HTML as browser would see it - java

I am trying to automate the process of printing shipping labels for our company. I have a program that takes an email and gathers all the information from it that we need and puts it in an HTML file. I am using HTML because we want to include our logo,a JPG file hosted online (If you know of a way to do this without using HTML that would work, please share). I then have that file set to automatically print to the default printer without showing a dialog box. The problem is, what prints out is the text of the file, meaning all the html tags print out. Here is my code( sorry its a bit messy, I will clean it up when I get it working).

import java.util.*;
import java.io.*;
import java.io.File;
import java.lang.Object;
import java.nio.charset.Charset;
import java.nio.file.Files;
import java.nio.file.Path;

public class Main2
{
    public Main2()
    {
        Path file = Paths.get("D:\\email\\2016.txt");
        ArrayList<String> text = new ArrayList<String>(1000);
        boolean stop = false;
        int i = 0;
        String line1;
        String line2;
        File myFile = new File("");
        try{
            File printme = File.createTempFile("printme", ".html", new     File("D:\\email\\output\\"));
            myFile.deleteOnExit();
            String pathName = (myFile.getAbsolutePath());

            BufferedWriter bw = new BufferedWriter(new FileWriter(printme));  
            bw.write("<html> <head> <meta name=vs_targetSchema     content=\"http://schemas.microsoft.com/intellisense/ie5\"><style     type=\"text/css\"> A { text-decoration: none; } A:link { color: #3366cc; text-    decoration: none; }   A:visited { color: #663399; text-decoration: none; }        A:active { color: #cccccc; text-decoration: none; } A:Hover { text-decoration:     underline; } BODY, TD, CENTER, P { font-family: Geneva, Verdana, Arial,     Helvetica; font-size: 12px; color: #333333; }    .body { font-family: Geneva,     Verdana, Arial, Helvetica; font-size: 10px; color: #333333; }  .content { font-    family: Arial, Helvetica, sans-serif; font-size: 11px; font-weight: normal;     color: #000000; }   .title { font-family: Helvetica, Arial, sans-serif; font-    size: 10px; font-weight: normal; color: #000000; } .headline { font-family:     Helvetica, Arial, sans-serif; font-size: 14px; font-weight: bold; color:     #000000; }    .message { font-family: Geneva, Verdana, Arial, Helvetica; font-    size: 9px; }    </style> </head><body bgcolor=\"#ffffff\" LINK=\"#3366cc\"     VLINK=\"#3366cc\" ALINK=\"#3366cc\" LEFTMARGIN=\"0\" TOPMARGIN=\"0\">    <table     cellSpacing=1 cellPadding=3 width=\"100%\" border=\"0\" runat=\"server\">    <tr>            <td colSpan=1><IMG src=\"http://www.eshanes.com//Images/eshaneslogo.jpg\"     border=0></td>    </tr>");

    }
}

Please help me fix this problem.

Thanks for the help, DebD! This did not solve my problem, but it led me in the right direction. Here is the code that worked if anyone needs it:

public static void print(File file) {
    JFrame frame = new JFrame();
    JEditorPane pane= new JEditorPane();
    pane.setContentType("text/html");
    try{
        pane.setPage(file.toURI().toURL());
    }catch (IOException ex){
        System.out.println("MALFORMED ERROR!");
    }
    frame.add(pane);
    frame.setSize(200,200);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setVisible(true);
    try{
        pane.print(null, null, false, PrintServiceLookup.lookupDefaultPrintService(), null, false);
    } catch (Exception e){
        System.out.println("PRINT ERROR!");
    }
}

What you seem to want is to parse the HTML, then do layout and rendering like a browser would. That's a fairly monumental task to undertake from scratch.

What you probably want is to find an existing layout engine that you can hand your HTML to and which will then return a rendered document/image/whatever.

You need to first render the HTML. You could use JEditorPane for that. Just set the content type to "text/html", set your content. Now, you get a snap of the rendered contents as below

JEditorPane jp = new JEditorPane("text/html", textString);
jp.validate();
int w = jp.getWidth(), h = jp.getHeight();
BufferedImage saveimg = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = saveimg.createGraphics();
jp.paint(g2);

Now, use the graphics object to print.
