A better approach would be to use an existing rendering engine from a browser, and then build a binary around it that can take a website as input and produce a PDF as output. That way you can get results consistent with how browsers would print a page and if you pick the right engine you'll not have to keep up with any changes to HTML standards, the engine developers will do that for you. This is essentially the approach wkhtmltopdf takes: it extracts the open-sourced Webkit renderer used inside browsers like Safari and Chrome and bundles it up into a Linux CLI application which produces some pretty impressive results. I thought I'd jump right in and start by compiling it on my Debian webserver. The wkhtmltopdf site has some instructions for building it on Ubuntu, which I thought were worth a try.

The specified command is then run using the X display corresponding to the Xvfb server just started and the X authority file created earlier. When the command exits, its status is saved, the Xvfb server is killed using the process ID stored earlierthe X authority cookie removed, and the authority file deleted if the user did not specify one to use.


Let's get started, shall we? Step 1: Install wkhtmltopdf and xvfb. # apt-get install wkhtmltopdf xvfb. Step 2: Create and enable the init script for the xvfb daemon. Step 3: Modify the PHPWkHtmlToPdf Wrapper. Step 4: RENDER!
