I'd seen this kind of thing before but voted up after checking out the 'advanced options' section. After some googling of those "man page" style options, I see now this is probably a web wrapper around [1] so I will more likely integrate that program directly into something I'm working on. But still bookmarking the site for quick jobs.
I've been researching ways to print the timelines on my site, Preceden. There's a complicated mix of HTML and CSS and, needless to say, it doesn't print by simply clicking Print on the browser:
Ooh -- if that works I could do my dashboards in HTML/CSS, print them to PDF, convert the PDF to an image file, and use that. That would make my life much easier, as producing the PDFs directly is a bit of a kludge. Thanks, I'll have to look into that later.
You should have a look at Flying Saucer/xhtmlrenderer (https://xhtmlrenderer.dev.java.net/). It handles every CSS rule I could throw at it. If you simply need a commandline app converting a XHTML file into a PDF, you're done in 10 lines of code.
