command line tool for generating pdfs from various document types?

Question

I'm looking for ways to generate pdfs on-the-fly preferably using a command line tool as this will be done from a web-based system.

My requirements include must work on Windows and Linux, should be able to convert Microsoft Word, Excel and HTML into PDF.

Also the ability to concatenate or merge various documents into one PDF output file would be good.

Any suggestions? I would prefer to avoid applications that work as "printer drivers".

many thanks

I think this has a command line utility, but not sure. Check this

Have a look at biopdf, and a PDF printer that uses it called Bullzip PDF. Check the documentation for Bullzip PDF for examples on how it can be automated. It has an API interface as well as the GUI.
