Hi,

The Epson WorkForce Pro WF-4730 All-in-One Printer could be connected via Wi-Fi, Ethernet, or USB. How do you wish to connect the printer?

If you have a Wi-Fi router, it should not be difficult to connect the printer wirelessly, or through Ethernet (to one of the LAN ports). Since the Epson WF-4730 is mentioned in About AirPrint - Apple Support as a model supporting the driverless AirPrint technology, you should not even need additional drivers. You could print from an iPhone/iPad as well via AirPrint.

Software/drivers from the printer manufacturer may or may not add functionality. Drivers are required for a USB connection.
