How can I get Windows 10 to see my wireless printer when on WiFi itself?

I just got an Epson WF-4640 wireless printer. It's installed and running on all of my Windows 7 machines and will connect whether on WiFi or ethernet. My Windows 10 box is a different matter. It's installed and running fine when the computer is connected to the network via ethernet, but if the computer's connection is WiFi, Windows cannot find the printer (I can't even ping the IP address). All other network functions are fine on WiFi, just the printing doesn't work. I think I had a similar issue with an HP printer on this same box.
Any ideas would be greatly appreciated.
Thank you.

Make sure the printer has a Static IP Address on your network. Set a static IP and then reset the printer (turn off and on) and ensure it has the address you set.

Now computers should find it.

Also, on the Windows 10 computer, Control Panel, Network and Sharing Center, make sure File and Print Sharing and Network Discovery are both set ON.

What are the IP addresses of the printer, a Win7 PC and the Win10 PC?

For the PCs, running IPCONFIG from a DOS prompt will show it. On the printer, you can print a Network Setup Report by pressing the Color or B&W button during network setup (see pg 41 of the User's Guide.

Also disable both your Windows 10 firewall and your security system's firewall and retest.

Printer is static 10.1.2.78
Win 7 PC 10.1.2.111
Win 10 PC 10.1.2.84

Both the Ethernet and the WiFi networks are defined as Domain on Win 10, and the file and printer sharing is on for Domains.

Try resetting TCP/IP and DNS Flush.

Open cmd.exe with Run as Administrator
Then netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer

The WiFi is integrated into our Sonicwall appliance. I looked at the zone settings and the WLAN and LAN are open bi-directional. Besides, I can access the printer via WiFi on my Win 7 boxes, which leads me to believe it's an OS thing as opposed to the router/firewall.
Does the Win 10 firewall have different settings for each connection? they're both set as Domains, so I'm not sure why they would react differently.

Also, under the covers, Windows 10 and Windows 7 in terms of printers and sharing are nearly the same

Ran the reset and flush and no difference.

Something appears to be wrong with your Windows 10 box. It should work essentially the same as Windows 7.

Try running System File Checker: Open cmd.exe with Run as Administrator and run SFC /SCANNOW. OK out and restart.

Nest, make a new, test Windows User Profile (Account). Log into the new Windows Account and test the printer there.

Next would be a Windows 10 Repair Install (easy to do).

I just installed the printer on another box that is EXACTLY the same (with Windows 10) and I get the same results. Good with Ethernet, no good with WiFi. I'll try the system file checker next.

Ramin

Can you disconnect the Ethernet and Retest ?

Helpful. It would appear the Windows 10 wireless NIC is not compatible with your Wireless access router.

Not sure why that worked, but a dinky d-link in AP mode did the trick.
Thank you so much (It was the CEO's computer that couldn't print so I was sweating).
Cheers!

Thanks for the update and I was happy to help you resolve this.
