The key here is to understand that the printer must become a full member of your local network. To do this, you must correctly assign it the SSID (network name) and password from your router. Unlike older models, which required a temporary USB connection to transfer settings, Epson L3156 It is equipped with a screen that allows for direct data entry, but the software part of installing drivers still requires attention to detail.
In this article, we'll walk you through the entire process, from unpacking to successfully printing over the air for the first time. We'll cover the intricacies of software installation and the utility's operating features. Wi-Fi Direct and methods for troubleshooting typical errors when a device simply doesn't see the router or refuses to print.
Equipment preparation and compatibility testing
Before proceeding with the software, you must ensure the hardware is physically ready. The device must be powered on, filled with ink, and the paper tray open. Wi-Fi indicator The indicator on the control panel should be lit or flashing, indicating the module is ready for operation. If the indicator doesn't respond, a factory reset of the network settings may be necessary.

If the device is new, the program will offer two options: setup via USB cable (a temporary connection to transfer the Wi-Fi password) or direct setup via the printer menu.
☑️ Pre-installation check
Setting up Wi-Fi via the device menu and USB cable
If the automatic search yields no results, you can use the classic method of transferring settings. To do this, you'll need to temporarily connect the MFP to your computer via a USB cable. Plug the cable into a USB 2.0 or higher port on your computer and the corresponding port on the back of the printer.
In the installer interface, select the option Set up via USB cableThe program will automatically read your PC's current network settings and transfer them to the printer.

Enter the password using the on-screen prompts. This method is convenient because it doesn't require a cable, but entering a complex password using the buttons can take time.
⚠️ Caution: When transferring settings via USB, ensure the cable is properly connected and firmly seated. Interrupting the data transfer at 80-90% may cause the printer's network module to freeze, requiring a reboot.
After a successful connection, the Wi-Fi indicator on the device's panel should turn green and remain lit. A blinking indicator usually indicates the connection is in progress or an error. If only the Wi-Fi Direct (smartphone) indicator is lit, and not the infrastructure network indicator, the printer has not connected to the router.
Using Wi-Fi Direct to print from your phone
One of the most useful features of the model L3156 is support Wi-Fi DirectThis technology creates a direct wireless connection between your smartphone and printer without a router. It's ideal for quickly printing photos from your phone when you don't have a computer or the internet is temporarily down.

What is the difference between Wi-Fi and Wi-Fi Direct?
Wi-Fi mode connects the printer to your home router, making it accessible to all devices on the network simultaneously. Wi-Fi Direct mode creates a separate access point from the printer itself. In Direct mode, the printer doesn't have internet access, so scan-to-cloud or voice control features may not be available.
It's important to understand the limitations: in Direct mode, the printer operates as an isolated access point. While connected, your phone may temporarily lose internet access (unless dual Wi-Fi support is supported). For everyday use in the office or at home, connecting via a router is preferable.
Table of indicators and connection error codes
Understanding LED signals on the panel Epson L3156 significantly simplifies diagnostics. The device communicates its status through a combination of blinking Wi-Fi and Wi-Fi Direct indicators. Don't ignore these signals, as they are the first source of information when troubleshooting.
Below is a breakdown of the network module's main states. Please note the color and blinking frequency.
