Air Print from iOS apps like Notes

I am currently running iPrint Appliance Version: and have all of my printers listed in iPrint set for Air Print and Mobile. When able to open a file up using the iPrint iOS app, printing working fine. However, when attempting to print via browse option for Air Print, no printers appear. It does not matter if the iPad is on the same vlan as the network printer or not. Am I missing something in my setup that goes beyond having the green checkmark next to each printer in the iPrint Appliance /iprintconfig/printers section? Thanks in advance for any insight for me to resolve or better understanding of the "Air Print" setting.
