Hi , Thank you for reaching out! My name is Stefano and it’s my pleasure to assist you today.
Is your iPad running the last firmware update, i.e. 26.1 ?
Are you trying to print World files, through iPad native apps or third parties ones ?
Besides, have you installed the latest iPad Ms Word App, i.e. 2.103.1 ?
Have you updated your AirPrint printer firmware to the latest one too ?
