Sometimes you need to print a document, but you don’t have a printer available – or I want to save it for your notes in a stable format that will never change. In this case, you can “print” to a PDF file. Luckily, macOS makes it easy to do this from almost all applications.
The Apple Macintosh operating system (macOS) has included system-level support for PDF files for 20 years now since the original Mac OS X Public Beta. The PDF printer feature is available from almost all applications that allow printing, such as Safari, Chrome, Pages, or Microsoft Word. Here’s how to do it.
Open the document that you want to print to PDF file. In the menu bar at the top of the screen, choose File> Print.
The printed document will then be saved as a PDF file in the location you selected. If you double click on the PDF file that you just created, you will see what the document looks like if you print it on paper.
