"Print" function on SMART CATALOG calls supported printer's driver for each of AirPrint for iOS, CloudPrint for Android, and Windows OS. Thus, please ask for the support to each of the printer vendors. SMART CATALOG does not support for this matter. The trouble shooting for AirPrint, click here for the reference.
In case your iOS version is old, or the firmware for the printer is not the latest, they may cause trouble.
