There are a couple of different ways to print, depending on the type of app you're using. For most apps, you'll use the Devices charm to print. If you're using a desktop app, you'll use the printing options that are built into that app.
Open the item you want to print.
Swipe in from the right edge of the screen, tap Devices, and then tap Print. (If you’re using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Devices, and then click Print).
If you receive a message saying This app can't print, the app you're using doesn't support printing.
Choose a printer from the list.
You’ll see a preview of what you're printing, along with the number of copies and the page orientation on the preview pane.
If you can't find the printer you want, you can add it. For more info, see Install a printer.
To see what else you can do, tap or click More settings.
The options in More settings differ for each printer, but you can typically change the paper type, page layout, print orientation, and other output settings. The options you see are made available by the printer manufacturer.
When you’re happy with the settings, tap or click Print.
Each desktop app determines how you print from that app, so the way to print will vary from app to app. Here are some of the most common ways to print from desktop apps:
Look in the File menu. It's very common for a Print option to be located in the app's File menu.
This might bring up the app's Print dialog box.
Look for a print icon or button. App manufacturers commonly put a print icon or button somewhere on the screen. These are commonly located on a toolbar positioned across the top or bottom of the app.
If none of those ways work, look at the documentation that came with the app or visit the app's help and support site to learn how to print.
