For what reason does my printer continue saying disconnected?

My Epson Workforce 545 is interfacing with our home system through our wifi, with an IP address.

The printer works delightful, with the exception of when it isn't utilized for several days, which it will say "Disconnected". Investigating in Windows 10 just says it's not controlled on, yet it unmistakably is. When I check the system status on the printer, it says still associated. I'm unfit to ping it when it says disconnected.

Now and again rebooting the switch will make it return, however more often than not I need to expel the printer totally, and re-include it physically utilizing the IP Address. It doesn't come up as an addable gadget for reasons unknown, which is the purpose behind physically including it.
