how to fix a printer spooling problem

Hi,

You do not say how the printer is connected (USB, Ethernet, or Wi-Fi).

The Epson ET-3850 is listed in About AirPrint - Apple Support as a model supporting the driverless AirPrint technology. This means that you should not have to install drivers, provided that the printer is connected to the same network (Wi-Fi router) as the Mac computer. The ET-3850 connection to the router can be wireless, or wired (Ethernet) to one of the LAN ports.

Drivers from the printer manufacturer are required if AirPrint is not used (for example, in case of a USB connection).

Add a printer to your printer list so you can use it on Mac – Apple Support (UK)

Reset the printing system on your Mac to solve a problem – Apple Support (UK)

I’m not sure if it’s an issue with your device, but rather an issue with your printer.
