PDF installed how to print multiple pdf slides per page simply print your presentation to it. If you don’t have it installed, you can obtain a copy from the Download page.
PDF is installed as a virtual printer so you can create PDF files simply by printing to it instead of your normal printer. During installation novaPDF gives the option to install an add-in for Microsoft Office. By default the option is checked and it will add in the supported Microsoft Office applications another tab called novaPDF that will let users create PDF files directly from the Office interface by simply clicking a button. The add-in installs itself with the default settings, but those can be modified if you need advanced customization of the resulting PDF. This lets you select which printer to use and if you want to save the document before converting it.
When checked, it will save any changes done to the currently opened document before doing the conversion to PDF. By default this option is checked. This section lets you customize how links will be detected and converted in the resulting PDF file. If this is checked, all links in the current document will be detected and converted as active links in the resulting PDF file. If checked it will convert links pointing to other documents.
