Printing is a pain in the rear. I hate managing stacks and stacks of paper, but sometimes I have to have an exact copy of an e-mail or webpage at my fingertips. This is where OS X’s print as PDF feature comes in really handy.
1) Depending on your application, go to the print menu (Usually Command + P or File>Print).
2) When the print dialog appears, move your cursor to the lower left-hand side of the window to find the “PDF” button. Click and hold the button.
3) You’ll get a drop down menu with about a dozen options. If you just want to save the page/e-mail/whatever out as a PDF, select “Save as PDF.”
4) Navigate to where you want the PDF to be saved. Now click the save button.
I use this tip to keep receipts of all of my online purchases. I don’t know what I’d do without it. Not to mention the money I save on paper and toner.
