Members who have experienced this problem usually find that it's due to the fact that your WiFi router changes the IP address of the printer occasionally and this 'confuses' the iPad. You need to log in to your router as Admin and tell the router to assign the printer a static IP address so that it doesn't get changed.
Good to hear from you. You’ll find a whole bunch of iPad enthusiasts in this Forum who are only too willing to help other iPad owners and to hear of their experiences. Don’t be afraid to post any questions you may have or use the ‘Search’ button near the top of the Forum web page. I usually find I discover one new interesting and useful piece of information about my iPad every day - and often not even what I was looking for!!
Hope to hear from you soon with your thoughts about the iPad.
Have fun and enjoy your iPad
