AirPrint primary escalation requirements

Before proceeding, make sure to fill out the Main escalation information requirement.

Gather the primary requirements for AirPrint‑related issues.

Before you begin

Make sure that your printer and iOS device are both connected to the same Wi-Fi network and within range before attempting to print.

Note:  Wi-Fi printers can take several minutes to join a Wi-Fi network after being turned on. For more information on printing from an iOS device, click here.

Verify that the iOS device and the app you are printing from are running the latest versions.

Verify that the AirPrint-enabled printer has the latest firmware version installed.

Additional notes

  • Certain printer features or functions may not be available when using AirPrint (e.g., selecting different paper trays, red-eye reduction, booklet printing, and so on).
  • AirPrint-enabled printers connected using Bluetooth or shared through a USB port of a Mac, PC, AirPort Base Station, or Time Capsule, are NOT supported.
  • Avoid connecting your printer to the USB port of Apple AirPort Base Stations or Time Capsules. Doing so can enable traditional AirPort printing from a Mac, but it will not enable AirPrint functions for iOS devices.

Note:  If you cannot use Wi-Fi networking to connect the AirPrint-capable printer, use an Ethernet connection from the AirPrint-capable printer to the Apple AirPort Base Station or Time Capsule.
