[thelist] On the fly PDF

I have a Perl/CGI system in place which products very nice HTML reports as
part of its functionality.  The client then prints those reports to PDF
before he prints to his physical printer.  Using PDF, he gets the correct
margins and page breaks etc. and the reports come out perfectly on his
physical printer(s).

I would like now to automate that step.  What I would like is a server-side
technology to convert the HTML we generate into PDF and then deliver that
PDF to the client's browser.  I have found products that do 'almost' this
functionality but not exactly. :)

Any suggestions?

Thanks,
Hershel
