Connecting your Epson L121 printer wirelessly on Windows 10 and Windows 11 can make printing much more convenient, especially if you want to print from multiple devices without dealing with cables. Although the Epson L121 is primarily a USB printer, you can still enable wireless printing by sharing it over a network or using a wireless print server. This guide will walk you through the complete process step by step.
Step 1: Check Requirements
Before starting, make sure you have the following:
- Epson L121 printer
- Windows 10 or Windows 11 PC
- WiFi network connection
- USB cable (for initial setup)
- Correct printer driver installed
If you haven’t installed the driver yet, download and install it. The Epson L121 Driver Download from the official source is the best way to ensure proper functionality.
Step 2: Connect Printer via USB
Since the Epson L121 does not have built-in WiFi, you must first connect it to a computer using a USB cable.
- Plug the printer into your PC
- Turn on the printer
- Wait for Windows to detect the device
Once connected, make sure the printer is working properly by printing a test page.
Step 3: Install or Update Printer Driver
To ensure smooth wireless sharing, install the latest driver:
- Open Settings → Devices → Printers & Scanners
- Click Add a printer or scanner
- Select Epson L121 from the list
If the printer is not detected, manually install the driver using the downloaded setup file.
Step 4: Enable Printer Sharing
Now you need to share the printer over your network:
- Go to Control Panel → Devices and Printers
- Right-click on Epson L121
- Select Printer Properties
- Go to the Sharing tab
- Check Share this printer
- Give it a simple share name (e.g., EpsonL121)
- Click Apply and then OK
Your printer is now available on the network.
Step 5: Connect Other Devices Wirelessly
To use the printer wirelessly from another computer:
- Make sure both computers are connected to the same WiFi network
- Open Settings → Printers & Scanners
- Click Add a printer or scanner
- Wait for Windows to detect the shared printer
If it doesn’t appear:
- Click The printer that I want isn’t listed
- Choose Select a shared printer by name
- Enter path: \\ComputerName\EpsonL121
Click Next and install the driver if prompted.
Step 6: Print Over WiFi
Once connected:
- Open any document
- Press Ctrl + P
- Select Epson L121 printer
- Click Print
Now you can print wirelessly without needing a USB connection on every device.
Alternative Method: Use Wireless Print Server
If you don’t want to keep your main PC on all the time, you can use a wireless print server.
How it works:
- Connect Epson L121 to a print server device
- Connect print server to WiFi network
- Install printer on all devices via network
This allows true wireless printing without depending on a host computer.
