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.
• Using some webservice on internet

For more information, see:
http://doc.tiki.org/General+Settings?structure=Tiki+Reference+Guide

Or instead, you can use free software PDF printers, such as:

• CUPS-PDF under GNU/Linux or Mac/OSX (see in your list of packages available): http://www.physik.uni-wuerzburg.de/~vrbehr/cups-pdf/
• PDF Creator under MS Windows: http://sf.net/projects/pdfcreator/

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.

You can also use PluginArchiveBuilder.

Since Tiki9, you have the option to print a slideshow directly in a PDF file. See: dompdf

To include a PDF in a page, see: PluginMediaPlayer

ViewerJS 

A new optional library to display pdf and other file types. See ViewerJS
