The recommended way to generate PDFs in Tiki is mPDF. This page still partially contains old deprecated information related to PDF creation and needs review.
For the Tiki part of PDF configuration see also General Admin under the "General Settings tab" section.
You can choose at PDF from URL between:
From Tiki 15.2, download and install (even on shared hosting) the mPDF PHP library (see mPDF ).
Using Qt Webkit with wkhtmltopdf which needs to be downloaded separately from http://wkhtmltopdf.org/ and uploaded to the server where Tiki is. Since it is needed you have to check whether the PHP function shell_exec is allowed to be executed under tiki-admin_security.php.
wkhtml is a C library and needs full root access on the Linux server to be installed.
With that PDF printer software, you can print a full structure of wiki pages (like a wiki book) to PDF. In addition, if you want to produce some nice table of contents for the paginated structure, you can do so easily by using a text editor such as Open Office. org. See the video tutorial in http://tiki.org/TikiWikiTV explaining the whole process.
