Important
Because some application software does not support AirPrint, Printer Options may not be

that application software.
Note
The printer options differ depending on the application software and model you are using.
Normally, when you tap Print and select a model name, the displayed printer options will include
up to the following four options:
Printer: Select a model that can be used in your wireless LAN.
Copies: Select the number of print copies.
Duplex Printing: If the model supports duplex printing, you can select On or Off.
