We have been struggling with a few different perl modules that are supposed to let us output PDF on our server. We want our users to be able to generate content with lots of formatting and pictures and then be able to convert it to a downloadable pdf. So far, everything we have tried out seems to have major problems handling any sort of formatting or graphics. I've found quite a few of the commercial products out there, but we are looking for something free that we can configure ourselves. Any suggestions?
