I have a client who is looking to create custom-generated newsletters and communications based on various research and reports gleaned from the web. Some of it will be content that we will own and can reside in a DB we'll have access to. Other content, all cleared and blessed by the owners, would be pulled in based on a user's profile.
Hope that gives you enough information. I have been looking for vendors that do just that and can't yet locate anything.
Thanks!

TCPDF has more powerful tools in terms of new content (it can make forms, import vector graphics, etc. and even sign files), whereas FPDF (and the extension FPDI) is much more basic, but can import existing PDF files as "templates", and write extra stuff on top.
