Connecting the Epson L355 Printer to Wi-Fi: A Complete Guide from A to Z

Connecting a printer Epson L355 Connecting to a wireless network is a challenge faced by both office workers and home users. This model combines printing, scanning, and copying functions, but its main advantage is its support Wi-Fi connections, allowing you to print wirelessly from any device. However, the setup process isn't always smooth: sometimes the router doesn't recognize the printer, sometimes the drivers refuse to install, or printing is delayed.

In this article we will look at all possible connection methods — from standard installation via the printer screen to manual configuration via the IP address. You will learn how to avoid common mistakes (for example, Error: Wi-Fi connection failed), which router parameters affect connection stability, and how to set up printing from a smartphone on Android or iOSAnd if something goes wrong, there's a section at the end with solutions to the most common problems.

Before you begin, make sure you have the following on hand: Wi-Fi password, the printer's power cable, and at least one device (PC, laptop, or smartphone) for testing printing. If the printer is new, don't forget to remove the protective stickers from the cartridges and ink tank!

1. Preparing the Epson L355 printer for Wi-Fi connection

Before setting up a wireless network, you must complete the following steps: initial printer preparationThis includes unpacking, installing the cartridges, and turning on the device. Skipping this step can result in errors such as Ink system error or Printer not ready.

Follow this algorithm:

• 📦 Unpack the printer and remove all protective elements (films, stickers, shipping locks). Pay special attention to the print head, as orange caps are often left there.
• 🖨️ Install the cartridges into the appropriate slots. For Epson L355 original ink is used T6741-T6744 (black, cyan, magenta, yellow). If you are using a CISS (continuous ink supply system), fill the ink tanks to the level MAX.
• ⚡ Connect the power cable and press the power button. Wait for the printer to complete initialization (the main menu will appear on the screen).
• 📄 Load paper of the following size into the tray A4 (70-90 g/m² is recommended). This will be needed for test printing.

If the printer has been used before, but you want to reconfigure Wi-Fi (for example, after changing the router), follow these steps: reset network settings:

1. On the printer control panel, go to Settings → Network settings → Reset Wi-Fi settings.
2. Confirm the action with the button OK.
3. Wait for the device to reboot (about 30 seconds).

2. Methods for connecting the Epson L355 to Wi-Fi: choosing the optimal one

Exists three main methods Wi-Fi settings on Epson L355, and the choice depends on your preferences and available equipment. Let's look at each of them:

The easiest way is using WPS (Wi-Fi Protected Setup). To do this:

1. Make sure the WPS indicator on your router is lit (usually the button is located on the back panel).
2. On the printer, go to Settings → Wi-Fi → WPS (Push Button).
3. Press the WPS button on the router, then confirm the action on the printer.
4. Wait for the message Connected to Wi-Fi (usually takes 1-2 minutes).

If your router does not support WPS or the feature is disabled, proceed to the next section for step-by-step instructions for manual setup.

What to do if the WPS button does not work?

Sometimes routers block WPS after several unsuccessful attempts. To unlock it, press and hold the WPS button for 10 seconds or reboot the router. If the feature is disabled in the settings, access the router's web interface (usually 192.168.0.1 or 192.168.1.1) and enable it in the section Wi-Fi → WPS.

3. Step-by-step instructions: connecting via the printer panel (manual input)

This method is suitable if you don't have a USB cable or your router doesn't support WPS. We'll enter the network name (SSID) and password directly on the printer screen.

Follow the instructions:

1. On the printer panel, press the button Settings (gear icon).
2. Select Wi-Fi → Wi-Fi Setup.
3. In the list of networks, find your Wi-Fi network (if it is not there, click Refresh or Other networks).
4. Enter your Wi-Fi password. Use the arrow keys to select characters. Please note: there is no language indicator on the printer screen - English is used by default.
5. Confirm your entry and wait for the connection to complete. A check mark and the printer's IP address will appear on the screen (e.g., 192.168.1.105).

If the printer gives an error Authentication error, check:

• 🔑 The password you entered is correct (case-sensitive!).
• 📡 Network security type: Epson L355 supports WPA2-PSK (AES)If you have WEP or WPA3, change the router settings.
• 🔄 Restart your router and printer, then try again.

4. Connecting via USB cable and Epson Software

This method is the most reliable if the previous ones didn't work. It requires temporarily connecting the printer to the computer via USB cable (included) and installation of proprietary software from Epson.

Instructions for Windows 10/11:

1. Download Drivers and utilities for the Epson L355 From the official website. You need:
   • 🖥️ Printer driver (for printing)
   • 🌐 Epson Software Updater (to set up Wi-Fi)

Connect the printer to your PC via USB and start installing the drivers. Follow the wizard's instructions, selecting the option Wireless connection.

After installing the drivers, open the program Epson Software (it will appear in the menu Start).

Select Wireless Network Setup → Connecting via USB.

The program will automatically search for available networks. Select your Wi-Fi network, enter the password, and click Next.

Wait for the setup to complete. The printer will reboot and connect to Wi-Fi.

For macOS the process is similar, but instead Epson Software Updater use Epson Printer Utility (available in App Store).

5. Setting up printing from a computer and mobile devices

Once your printer is successfully connected to Wi-Fi, you need to configure the devices you'll be printing from. Let's look at the process for different platforms.

🖥️ Setting up on Windows

If you used Epson Software To connect, the drivers are already installed. Otherwise:

1. Open Settings → Devices → Printers & Scanners.
2. Click Add a printer or scanner.
3. Find in the list Epson L355 (should appear automatically). If it is not there, click The printer you need is not listed. and select Add a printer by TCP/IP address.
4. Enter the IP address of the printer (you can find out by printing Network report from the control panel).

📱 Setting up on Android/iOS

To print from your smartphone, install the official app Epson iPrint:

• 📱 Download for Android
• 🍎 Download for iOS

After installation:

1. Open the app and tap Add a printer.
2. Select Epson L355 from the list of found devices.
3. To print photos or documents, use the corresponding tabs in the application.

6. Troubleshooting: Why the printer won't connect to Wi-Fi

Even with proper setup, problems may arise. Below - list of the most common mistakes and ways to solve them.

If the printer connects to Wi-Fi, but Printing is delayed or breaks off:

• 📶 Check the Wi-Fi signal strength on the printer (in Settings → Network Settings → Wi-Fi Status). If the signal is weak (1-2 bars), move the printer closer to the router.
• 🔄 Change the Wi-Fi channel in the router settings (recommended channels 1, 6 or 11 for the range 2.4 GHz).
• 🖨️ Update your printer firmware via Epson Software Updater.

How to check the IP address of a printer?

On the printer control panel, go to Settings → Network Settings → TCP/IP Settings. The current IP will be indicated here (for example, 192.168.1.103). Alternatively, print it out Network report (on the menu Settings → Print reports).

7. Optimize Wi-Fi for stable printing

To avoid connection problems in the future, configure your router to suit your printer's operating features:

• 📡 Use range 2.4 GHz (and not 5 GHz), because Epson L355 does not support 5 GHz.
• 🔒 Disable the feature Quick switching between ranges (if any), so that the printer does not get "lost" when changing frequencies.
• 🔄 Enable IP address reservation for the printer in your router's DHCP settings. This will prevent the IP address from changing during a reboot.
• 🛡️ If there are many devices on the network, limit the bandwidth for the printer (QoS) to 5 Mbps - this is enough for printing.

Also useful update your printer firmware regularlyTo do this:

1. Download the latest firmware version from Epson website.
2. Connect the printer to your PC via USB.
3. Run the firmware file and follow the instructions.
