Cannot connect to Epson wifi printer from Win10 notebook

Hi,

I'm trying to install an Epson WF3520 Printer, connected to my network by wifi, onto a Windows 10 ACER laptop. (Anniversary update, and all other updates installed.)

The printer, laptop and other computers on the network are all using reserved DHCP addresses. From the notebook, I can ping the gateway, as well as other computers on same network. I cannot ping the ip address of the printer (timeout). From another computer on the same network, I can ping the printer and gateway, 2 other computers (1 wifi, 1 ethernet), but cannot ping the notebook (also, timeout).

The printer is already installed and working on other computers on the network, both wifi and ethernet, although I did have to remove and reinstall the printers on all other machines yesterday for unknown reasons. The printer was showing as offline on all computers - no idea why! AFAIK, this only happened over the last couple of days.

I have......
- verified all IP addresses using ipconfig, and also checking the router device list.
- uninstalled the printer from the notebook, then attempted to add new printer. Port not found.
- manually added new port by IP address. Printer installed but not responding (no test page).
- done a Network Reset on the notebook
- rebooted the router
- updated notebook adapter device driver (Realtek RTL8723BS Wireless LAN 802.11n SDIO Network Adapter). No update available
- run out of ideas!

Any help would be appreciated. Thanks!

Well, that was very simple! Thanks very much for the tip. I have no idea how my network came to be public on that computer, but, once I changed that, the printer immediately appeared!

Thanks again!
