PDFs are the de facto standard for portable read-only document exchange. You can shell out money for Adobe or some other third party utility or, you can follow these steps to easily create a PDF from any OSX application that allows you to print a hard copy.
- Open a program that supports print
- Select Print
- In the bottom left hand corner of the Print dialog there is a PDF button, click it

It presents numerous options for manipulating a PDF file. You can save the PDF to disk, email it or any other number of things.
I use this feature all the time for printing receipts from the web, emailing a receipt to someone, making a PDF version of a Word document, etc. If you have any creative ways to use PDF, please let us know.
