How to print double-sided

Open Settings > Bluetooth & devices > Printers & scanners, select your printer and choose Printer properties (Windows 10: Settings > Devices > Printers & scanners, select the printer, then Manage). If there's a Device Settings or configuration tab with a duplex unit option, make sure it's set to installed. Many inkjet drivers don't have this option and detect the duplexer by themselves.

In your app, press Ctrl + P, choose the printer and open Printer Properties or Preferences. Look for Print on both sides, Two-sided or Duplex, usually on the layout, main or finishing tab. In newer Windows apps that use the simpler print window, open More settings and look for a two-sided or duplex option.

Choose flip on long edge for portrait pages, so they turn like a book. Choose flip on short edge for landscape pages, or for portrait pages you want to flip upward like a notepad. If the back of each page comes out upside down, switch to the other edge.

To print on both sides every time, open the printer in Printers & scanners, choose Printing preferences and turn on two-sided printing there. Apps use this as their starting setting, and you can still switch a single job back to one-sided in the print dialog.

Many drivers offer a manual two-sided option: the printer prints the first side of every sheet, then shows a message explaining how to turn the stack over and put it back. Follow that picture exactly, because the correct way to reload depends on the printer's paper path. Let inkjet pages dry for a minute and fan the stack first so the sheets feed cleanly.

Choose File > Print, pick your printer and turn on Two-Sided, which appears as a checkbox or pop-up menu depending on the macOS version and the app. On macOS 12 and earlier, click Show Details first if the dialog is small. To choose the binding edge, open the Layout section and pick long-edge or short-edge binding.

The option only appears when macOS knows the printer can duplex. Open Apple menu > System Settings > Printers & Scanners, select the printer and click Options & Supplies; if the Options tab lists a duplex unit, tick it. If that doesn't help, remove the printer and add it again using AirPrint or the maker's current driver.

Once two-sided printing is set the way you like, open the Presets menu in the print dialog and save the current settings as a preset, for example Double-sided. Choose that preset next time instead of setting each option again.

Without a duplexer, open the Paper Handling section and set Pages to Print to Odd Only. Print, turn the stack over and reload it the way your printer requires, then print again with Even Only. Try it with a short numbered document first, and change Page Order if the even pages come out in reverse.

In Word for Windows, choose File > Print, then change the menu that reads Print One Sided to Print on Both Sides with the flip edge you need, or to Manually Print on Both Sides if there's no duplexer. Word for Mac uses the macOS print dialog, so turn on Two-Sided there.

Most PDF readers, including Adobe Acrobat Reader, show a Print on both sides of paper checkbox in their print window, with a choice of flip edge. If yours doesn't, open the printer properties from the print window and turn on two-sided printing in the driver.

In most browsers' print preview, the two-sided option sits under More settings and only appears when the browser can tell the printer supports it. If you can't find it, choose the option to print using the system dialog, which opens the full driver settings, or save the page as a PDF and print that.

Tap the share button, then Print, and choose your printer. If it supports automatic duplex, a Double-sided switch appears in the options; turn it on. If the switch is missing, the printer may not offer duplex over AirPrint, so try the maker's own app.

Choose Print from the app's menu or share options, select the printer, then tap the small arrow to expand the settings. Set Two-sided to long edge or short edge. The exact wording varies by phone and print service.

Printer makers' own apps usually have a two-sided setting in their print options, and some guide you through manual duplex on printers without a duplexer. They're worth trying when the phone's built-in print option doesn't show duplex.
