I am currently working on an online PDF document generator which allows you to enter rich text (MS word style) and then save as PDF format. Also – the beauty of PDF docs is that you can save the file onto your local machine or print it real time.
The rich text editor is a lite version of MS word, and it has most of the frequently used features according to my knowledge. Please give me a shout if you think some other features would be good to have. 
Nice site!
