This option is best for a single page or small selection of pages. Wiki pages print best when you select the "Printable version" option from the list of Print/Export options at the left of your screen. Once you see the simplified page of content, print the page using your browser's print function (Ctrl+P for PCs). This is the simplest way to print of information to read later.

If you just want a PDF of the wiki page you are on, select "Download as PDF". This creates a single PDF file quickly and without further steps required on your part. (The file itself may be one or several pages long depending on how much content is on the wiki page.)
