HTML Table to PDF (PHP Code)

We have a complex web-based php product, part of which is a reporting suite. Currently, we have scripts that generate HTML tables for output to screen. We have a requirement to add an Export to PDF option to these reports. This feature needs to be launched from the screen version and export to a A4 Landscape PDF and fit to one page wide, possibly multiple pages long (depending on the number of records in the report). We would like the ability to specify manual page breaks on the report that will be reflected in the PDF. We will supply an example HTML table that is being produced, but the system will need to accurately reproduce any HTML table that is passed to it in this manner.

External Libraries may be used, as long as they are free for commercial use. If they require a license to be purchased for commercial use, then this MUST be cleared with us before work commences.

The final solution MUST be compatible with our server setups, which include the following specification:

PHP Version 5.2.6
MySQL version 5.0.32
Apache Version 2.2.3
Debian Version etch AND Ubuntu 10.04 LTS

APC is installed for PHP, so there cannot be any conflicts.
