I have the Answer.
After 3 hours of looking on Apple support and Epson support and installing, re-installing software, updates, etc etc.
I have a Epson WorkForce 7620 printer that is suppose to be air print ready and couldn't get air print to work on my iPhone/ipad/or mac.
After installing Epson software and going through the set up process the "add printer" would only recognize the printer as a "Fax Printer". I could enter the IP address manually and was able to print from mac and iPhone using "pro printer" app. I was not able to print from iPhone "Notes" by selecting the "Print". Notes could not find an "Air Print" printer.
After almost 3 hours of frustration and 3 transfers with EPSON tech support, the problem was resolved in less than 5 minutes.
1. Print out your test page on your printer that will give you the network IP address and Default Gateway.
2. Use an iPad, iPhone, or Mac and open Safari. (Tech guy had me use iPad because I was on the iPhone)
3. Enter IP address into your safari Browser example ip address (111.158.1.23) I made up the numbers for an example.
4. You will get an error message. click on the bottom option "continue".
5. You should see an Epson WF-7620 Series on the top. Go down to the "Basic Settings" on the left hand side of the screen.
6. Go down to the "AirPrint Setup"
*Steps 7 and 8 might be reversed I am going through the steps and Enable AirPrint is grey and I can't remember which order I did it with Technical support.
7. Top Priority Protocol: it is directly above the "OK" button. Click on the arrow to the right and select "Port9100"
8. Enable "Enable AirPrint"
9. Select "OK"
10. Select "Back to Main"
You should now be able to open "Notes" and select print and see your WF7620 printer which is now able to AirPrint.
Hope that helps and saves you frustration, and time.
