Troubleshooting Question

Connecting Epson Printer to my Computer

58 Views
Last Modified: 2020-08-12
I had this working at one time. With the WFH changes and some finagling I did initially with my home computer, I somehow lost the connection to my Epson Workforce printer. I have Google internet and am using a Nest router and mesh system. I can print from my wireless devices to the printer. My home computer is tied into the router through one of the Ethernet ports. I used to be able to print from my home computer even though it does not have wireless capabilities. I can no longer do that.
I've gone so far as uninstalling the Epson drivers and trying to reinstall, but my home computer cannot find the printer. I've followed all the steps I can find online but am at a loss as to how to fix this. For now, I am emailing myself documents and opening and printing from my phone. Not the best way to do it.

If the printer is connected to the network via WiFi, then it's possible that WiFi to hardware bridging is not enabled (or has been disabled) in one or more routers, firewalls or bridges.

Diagnostic:  Scan the network using Angry IP Scanner or equivalent and see if the printer can be seen from the PC.  If not, connect the printer to the network via hardwire Ethernet.  Power-off restart both printer and PC and scan again.  If the PC can find it on the hardwire, then it's a bridging issue.

Possible workaround:  If the printer is within 20 feet of the PC, use the USB interface instead.  USB almost always sets up correctly.

Side note:  I'd want the printer connected to the hardwire Ethernet instead of WiFi.

I can see 2 possible problems:

  1. The printer only allows either WiFi or wired connections, not both. Most printers behave that way. To see if yours is different we need the model number.
  2. The (wired) IP address of the printer has changed. This can happen if the printer if the printer gets its IP address via DHCP. Print a config page on the printer to see its address. If you want us to tell you how to print a config page, or how to set the printer up with a static address, we need a model number.
More questions. Before the problem, were you able to print via both WiFi and wired interfaces? What else has changed in your setup since before WFH?

I've run into this scenario many times.  On the initial setup, Windows sets up the "Port" to use a method that finds the printer on the network.  That works for a while, then eventually it fails.

My solution is to set a static IP address on the printer and print to that IP address.  The steps are as follows;

Set a static IP on the printer.  My preferred method is to set up a reservation for it on your DHCP server (likely your router) so that it always has the same IP address.  If your router doesn't support this, the alternative is to go into the system on the printer itself and set the static IP.

In Control Panel, Devices and Printers (I'm assuming Windows here), right-click on the printer, left-click on Printer Properties (not "properties").  Click on Ports (tab at the top)

click on Add Port, standard tcp/ip port, New port, next
For the Printer Name or IP Address, type in the IP address you set up on the printer, then Next
Wait for it to find the printer and then continue with the settings it found

If you need help on picking an IP address, do the following:
Hold the Windows key down on the keyboard and tap R
Type: cmd
then hit Enter
Type: ipconfig /all
Let us know the IPv4 address (you may have to scroll up to find it) and Subnet Mask.  From that we can suggest an IP address to test and to use.


I would agree with Dr. Klahn that a wired connection (if your printer supports it) would be a preferable connection method for the printer.  Your wireless devices will still connect to it.

I'd also agree with his comment about a USB cable.  I generally recommend that people have cables for both so that you can get printing done when WiFi isn't working on the printer.

The interesting thing is everything has worked fine for years (bought this printer 3-4 years ago). Wireless printing from phones, tablets, my wife's Surface Pro and from my computer, which is hard wired into our network. Just stopped working. The printer is on an altogether different room than my computer so hard working it is not an option. Besides, Epson states it is one or the other, Wi-Fi or Ethernet.

hdhondt makes an excellent suggestion about printing the config sheet.  That will make it clear which interface is active and what IP address it has.  That should be a very quick thing to do.

If this just stopped working recently I wonder if any Windows related updates triggered a change on both your computer and your Wife’s Surface Pro. Can you check your Windows Update history refer to the below if needed:
