Who I have the same questioned this topic

Have had issues getting Air Print to work from IPhones ever since switching to Verizon Home Internet. Printer is supported and have had it work briefly and then 'No printer found' error minutes later. In researching, found one line in a troubleshooting link that stated   'Cellular Networks do not currently support AirPrint. '  Are there any directions to make this work. Thanks in advance-
