IPads running iOS 8.1 feature AirPrint technology, which supports printing wirelessly to AirPrint-compatible printers. If you don't have an AirPrint-compatible printer, install third-party software on your computer and use it to send jobs to your printer.
AirPrint is a technology designed to enable you to print wirelessly from computers and mobile devices. The vast majority of modern printers are equipped with AirPrint. Visit Apple's About AirPrint page for a list of AirPrint-compatible printers. If yours is on the list, turn it on and get it ready to print. Use your printer's controls to join the same Wi-Fi network as your iPad.
Printing to an AirPrint Printer
Before you can send a print job from your iPad, join the same Wi-Fi network as your AirPrint printer. To do this, open the Settings app, tap "Wi-Fi" and select the network on the provided list. Enter the network password, if prompted. Once you're on the network, open the iPad app containing the document or image you want to print, tap the app's "Share" or "Settings" icon and tap "Print." You may have to scroll through the sharing icons to locate the Print icon. Select your printer on the list of available devices, enter the number of copies you want to print and tap the "Print" button to send the job to your printer.
Monitoring and Canceling AirPrint Print Jobs
Once you send a job to an AirPrint printer, you can monitor its status using the Print Center on the iPad. To open the Print Center, press the "Home" button twice and then touch "Print Center." The badge overlaid on the Print Center icon indicates how many jobs are currently awaiting printing. To cancel a print job, tap it in the Print Center and select "Cancel Printing."
Printing to Non-AirPrint Devices
If you don't have an AirPrint-compatible printer, other options are available. Connect the printer to your Windows PC or Mac and install third-party software such as O'Print, HandyPrint or Presto. With these or similar programs installed on your computer, you can print wirelessly from the iPad without having to physically transfer documents and images onto the computer. However, if you're uncomfortable installing or paying for third-party software, you can also transfer photos and documents to your computer via email or cloud-based storage platforms such as iCloud or Dropbox and then print them manually.
