HTML2PDF allows you to take existing html output (with some limitations) and create a PDF file. If you are working in PHP, then the html that is used to create a screen display can be used to create a PDF file.

Using it is as simple as:

require('html2fpdf.php');
$pdf=new HTML2FPDF();
$pdf->AddPage();
$pdf->WriteHTML($strContent);
$pdf->Output("examples/$f_out");

What works

• Text using local font definitions or styles
   
• Tables
   
• JPG and PNG graphics

Limitations

• It doesn't seem to accept linking a "style" module so you have to put styles in-line.
   
• Tables are generated using a single font and size. Borders are limited to on and off.
   
• Gif images don't work (fatal error in generation). bmp and tif not supported. 

See the FAQ on the HTML2PDF website for more on limitations.

Extra Features

• The <newpage> command can be inserted to force a skip to a new page.
   
• Pages are numbered.
   
• A PDF bookmark page title can be added.

More Notes

I captured some observations when I was testing this system. See the notes here. 

Credits

• I haven't changed the system itself. I have added some notes on using it and some extra examples.
    
• The system was actually written in two parts. The underlying system is called FPDF and the site can be found at: http://www.fpdf.org/
    
• HTML2PDF interprets the html and uses FPDF to create the PDF file. It can be found at: http://html2fpdf.sourceforge.net/
