Applies to: Rectangular portrait or landscape sheets with conventional two-sided printing. Driver icons, manual-feed order and mixed-orientation handling require a short physical test.
For a normal portrait document that turns like a book, flip on the long edge. For pages that turn upward like a notepad or calendar, flip on the short edge. Landscape documents depend on how you want them bound.
Think about the binding edge
The setting describes the edge that acts like a hinge—not necessarily the longest-looking edge on your screen after rotation. Visualize how the finished sheet should turn.
Long-edge binding is the usual choice for portrait reports. Short-edge binding is typical for portrait pages that flip upward.
Choose by layout
- Portrait book or report: long edge.
- Portrait notepad or wall calendar: short edge.
- Landscape pages turning sideways like a book: short edge.
- Landscape pages flipping upward: long edge.
- Mixed-orientation PDF: run a two-page test before printing the full document.
Make a two-page test
Mark the top of two scrap pages, print pages 1 and 2, and turn the sheet the way a reader will. If page 2 is upside down, switch the binding-edge option.
Printer drivers use slightly different names. Some show icons instead of “long” and “short,” so verify the preview rather than relying only on wording.
Manual duplex printing
If the printer lacks automatic duplexing, print odd pages first, reinsert the stack, and print even pages. The correct reinsertion direction varies by printer path.
Test with two sheets and write down the working orientation. Avoid experimenting with an entire document.
Choose the hinge, not just the word “book”
The long edge changes position when the page changes orientation. In portrait, the long edges are at the sides; in landscape, they are at the top and bottom. Choose the physical edge around which the finished sheet will turn.
| Page orientation | How you turn it | Typical driver setting |
|---|---|---|
| Portrait | Sideways like a book | Long edge |
| Portrait | Upward like a calendar | Short edge |
| Landscape | Sideways like a book | Short edge |
| Landscape | Upward like a calendar | Long edge |
Make the two sides unmistakable
Create two pages labeled FRONT — TOP and BACK — TOP, each with an arrow pointing upward. Print those two document pages on one physical sheet. Turn it around the intended binding edge without rotating the sheet in your hands. Both arrows should still point to their own page tops.
If the back is inverted, switch only the flip-edge option and repeat. If the pages are in the wrong order but upright, changing the flip edge will not fix order; inspect reverse printing and booklet settings instead.
Manual duplex needs a different test
Mark one corner of a blank sheet lightly with a pencil and print a front. Note which face receives ink and which edge enters first. Reinsert it for a back test before printing an odd/even batch.
A printer that delivers pages face down may require a different stack order from one that delivers face up. Use your observed path and application instructions. Do not scale a successful single-sheet test into a large job without confirming page order on a short packet.
