Apps don’t have to support PDF output, they just have to support the normal printing features. You don’t actually print anything, but the idea is that an exact replica of what would have appeared on paper, if you had sent a job to a real printer, is instead stored as a PDF file.Ī big advantage of Print to PDF, or Save to PDF as it is often known, is that it is available in a lot of apps by default. Print to PDF is an easy way to preserve the information and layout of what you are currently viewing, saving a 1:1 digital copy of the documents and websites you use everyday.
