How to connect an Epson L355 printer to your phone via Wi-Fi: a complete guide with all the details

Printer Epson EcoTank L355 — a popular model with a continuous ink supply system, ideal for home or office use. One of the device's key advantages is the ability to print wirelessly from mobile devices. However, many users encounter difficulties when first connecting the printer to their phone via Wi-Fi. In this article, we'll cover all setup steps—from preparing the equipment to printing your first document—and also cover common errors and troubleshooting solutions.

It is important to understand that the connection process may differ depending on the operating system of your smartphone (Android or iOS), printer firmware version, and even router model. We'll describe in detail a universal algorithm that works in 90% of cases, as well as provide recommendations for non-standard situations. If you've never set up network printers before, don't worry: the instructions are tailored for beginners, with step-by-step screenshots and explanations.

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

Before connecting the printer to your phone, you need to configure the device itself correctly. Epson L355 supports two Wi-Fi connection modes:

• 📶 Infrastructure mode — the printer connects to your home router (recommended option for stable operation).
• 🔄 Access point mode (Wi-Fi Direct) — the printer creates its own network to which the phone connects (convenient for one-time printing without a router).

For most users, the first option is optimal. To activate it:

1. Turn on the printer using the power button and wait until the self-test is complete (the lights will stop flashing).
2. On the printer control panel, press and hold the button Wi-Fi (antenna icon) for 3 seconds until the indicator starts flashing slowly.
3. Click the button WPS on your router (usually it's located on the back panel). You have 2 minutesso that the printer and router “see” each other.

After successful connection the indicator Wi-Fi the printer will light up green (or blue, depending on the firmware version). If the light continues to flash orange, the connection is not established. In this case, check:

• 🔌 Is the printer's power cable connected correctly (sometimes failures occur due to an unstable power supply).
• 📡 Does Wi-Fi work on other devices (phone, laptop).
• 🔒 Is "client isolation mode" enabled on your router (it blocks communication between devices on the local network).

2. Installing software on your phone

To print from a mobile device, you will need the official app. Epson Smart Panel (For Android) or Epson iPrint (For iOS). These utilities not only provide communication with the printer but also provide additional functions: document scanning, ink level checking, and error diagnostics.

Download the app from official stores:

• 🤖 Epson Smart Panel on Google Play (requires Android 5.0 and above).
• 🍎 Epson iPrint in the App Store (compatible with iOS 11.0+).

After installation, launch the application and follow the setup wizard:

1. Accept the license agreement and allow access to files/photos (required for printing documents).
2. In the main menu, select Add a printer → Search the web.
3. If the printer is not found automatically, click Add manually and enter its IP address (you can find it out by printing it out Network settings from the printer panel).

During the connection process, the app may request access to your phone's location. This is necessary to find the printer on the local network. allow access, otherwise the connection will fail. If you decline, you'll have to enter the printer's IP address manually.

3. Setting up the printer via Epson Software Updater (alternative method)

If automatic connection via WPS does not work, use the utility Epson Software UpdaterIt allows you to manually configure the printer's network settings and update its firmware. Download the program from Epson's official website (select model L355 in the list of devices).

Connect the printer to the computer via USB cable (included) and follow the instructions:

1. Launch Epson Software Updater and select Setting up a wireless network.
2. Please enter the name of your Wi-Fi network (SSID) and password. If the network is hidden, check the box. Hidden network.
3. Wait for the settings to be applied (the printer will reboot).
4. Disconnect the USB cable and check the connection status on the printer control panel.

This method is more reliable than WPS, as it eliminates errors related to router settings. However, it requires a temporary connection to a PC. If you don't have a computer, try resetting the printer to factory settings (hold down the button). Stop 10 seconds) and try connecting again via WPS.

What should I do if Epson Software Updater doesn't detect my printer?

Make sure you are using an original USB cable (not all cables support data transfer).

Try a different USB port on your computer (preferably on the back of the system unit).

Disable your antivirus—it may be blocking the utility.

Check if the printer is detected in Device Manager Windows (Printers section).

• 🔄 Double-sided printing — if a duplex module is available.
• Click Seal and wait for the task to complete.

For iOS the algorithm is similar, but in the appendix Epson iPrint Additional features are available, such as printing from iCloud or Google DrivePlease note that when printing large files (e.g., 50+ page PDFs), the connection may be interrupted. In this case, split the document into smaller parts or use a USB connection.

5. Typical errors and their elimination

Even with proper setup, users often encounter problems. We've compiled a list of the most common errors and solutions:

Error	Cause	Solution
Printer not found	The devices are on different networks or Wi-Fi is disabled on the phone.	Check your connection to one network, reboot your router
Connection error (0x97)	Printer firmware failure or router blocking ports	Update firmware via Epson Software Updater or disable the firewall on your router
Printing interrupted	Weak Wi-Fi signal or low printer memory	Move your phone closer to the printer or reduce the file size.
Unable to print photo	Unsupported image format (e.g. RAW)	Convert photos to JPEG or PNG before printing

If the printer is connected but printing does not start, check:

• 🖨️ Ink level in the tanks (on the printer panel or in the app).
• 📃 There is paper in the tray (the sensor may not work if the paper is not loaded tightly).
• 🔌 Connect to the power supply (the printer must be plugged into a power outlet, not into the computer's USB port).

4. Launch the application Epson Smart Panel and select the printer manually.

In mode Wi-Fi Direct The data transfer speed is lower than when connected via a router, so large files may take longer to print. Additionally, in this mode, the phone will not have internet access. To return to normal operation, press the button. Wi-Fi on the printer again.

Why might Wi-Fi Direct not work?

Some phones (especially older models running Android 6 and below) do not support this protocol.

If the network DIRECT-xx-Epson_L355 does not display, update the printer firmware.

There may be too many Wi-Fi networks in the range (move the printer to another location).

7. Printing Optimization: Tips for Saving Ink and Time

Printer Epson L355 is known for its low printing costs thanks to its system EcoTank, but even here you can save resources. Here are some practical recommendations:

• 🖼️ For drafts, use the mode Quick Print (30% less ink consumption).
