The first screenshot looks like it is ready to fax - note the Fax button instead of Print. I don't think you need to print to a Fax PDF first.
To access the Epson Fax Utility, check out page 169 of the manual:
1. In the Apple menu or the Dock, select System Preferences. Select Print & Fax or Print & Scan, select the FAX option for your product, and select Options & Supplies. Select Utility and select Open Printer Utility."
2. Double-click FAX Utility.
3. Select your FAX product in the Printer list.
4. Select Fax Settings.
5. Follow the prompts that appear on the screen to enter your fax header information and select your fax settings.
-Do you have a phone line connected to the Epson?
-Did you do follow/complete all the fax setup instructions in the manual?
