How to print a PDF double-sided (on both sides)

Quick answer: In the print dialog, turn on Print on both sides (or Two-sided) and choose Flip on long edge for normal portrait documents. If your printer cannot print both sides, print odd pages, put the stack back in and print even pages. Online, just choose “Double-sided” on PrintPDFOnline, where each side is 20% cheaper.

Automatic double-sided printing

1. Open the PDF and press Ctrl + P (Cmd + P on Mac).
2. Turn on Print on both sides of paper / Two-sided / Duplex.
3. Choose Flip on long edge for portrait pages, Flip on short edge for landscape pages.
4. Print.

Manual double-sided printing (printer without duplex)

1. In Adobe Acrobat, open More options and set Odd or even pages to Odd pages only. Print.
2. Take the printed stack and put it back in the tray, blank side facing where the printer prints, top edge in first. Print one test sheet first if you are unsure.
3. Set Even pages only and tick Reverse pages if the order comes out backwards. Print.

If the PDF has an odd number of pages, add a blank page at the end so the last sheet lines up.
