I found this nice project in google code repository. Please have a look
jsPDF is an open-source library for generating PDF documents using nothing but Javascript. You can use it in a Firefox extension, in Server Side Javascript and with Data URIs in some browsers.
More examples and features to come. Get in touch if you'd like to help out! :)
See Demo
Client-side demo works best in Safari or iPhone Safari. Also works Firefox 3 on Windows and Opera. IE support on the way.
Server-side will work anywhere. See example of PDF generated in Jaxer.Source : http://code.google.com/p/jspdf/
