Summarize the following:
Tap the app icon for the app in which the item you want to print is located.  For example, if you want to print a photo, you would tap the {"smallUrl":"https:\/\/www.wikihow.com\/images\/f\/f5\/Macphotosapp.png","bigUrl":"\/images\/thumb\/f\/f5\/Macphotosapp.png\/30px-Macphotosapp.png","smallWidth":460,"smallHeight":460,"bigWidth":"30","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of a Mac icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Fair_use\">Fair Use<\/a><br>\n<\/p><\/div>"} Photos app icon. Not all apps support printing, but the majority of the iPad's built-in apps should allow you to print. For example, if you're printing from the Photos app, you'll tap the photo you want to print. If you're printing a web browser page, you may have to tap ⋯ to open a menu before proceeding. It's usually in one of the corners of the screen, though you may find it in the URL bar or the ⋯ menu if you're using a browser. You'll see a pop-up menu appear at the bottom of the screen. This printer-shaped icon is in the bottom row of the pop-up menu. Doing so opens the Print menu. You may have to swipe from right to left across the bottom row of app icons in the pop-up menu to find the Print option. It's a field at the top of the menu. This will open a list of the compatible AirPrint printers within range. Tap the name of the printer with which you want to print your item. If you can't find your printer, make sure that the printer is on, connected to Wi-Fi, not connected to Bluetooth, not hard-wired to a router, and within range of your iPad. It's in the top-right corner of the screen. Your item will begin printing. Depending on your printer, you may have the option to select color or black-and-white printing, a page range, and so on before tapping Print.

Summary:
Open the app you want to use. Open the page or document you want to print. Tap the "Share"  icon. Tap Print. Tap Printer. Select your printer. Tap Print.
