Modern office equipment has long ceased to be simply peripheral devices that require a desktop computer for control. Wireless printing has become the standard for instantly sending documents and photos directly from a smartphone or tablet. However, owners of the popular model Epson L355 often encounter difficulties during initial setup, as this printer does not support Wi-Fi Direct technology, operating exclusively in infrastructure mode.
This means that for a successful connection, your mobile device and printer must be on the same local network broadcast by the router. In this article, we'll detail the connection algorithms for Android and iOS operating systems, as well as examine specific router configuration nuances that often become barriers for users. Understanding how network protocols work will help you avoid common mistakes and ensure stable operation of your equipment.
Before proceeding with software settings, you need to make sure that the hardware is physically ready. Make sure that the printer Epson L355 The continuous ink supply system (CISS) is installed correctly, the air valves are open, and the ink level is sufficient for testing. It's also critical that the router is turned on and working properly, as it acts as the intermediary between your phone and the printer.
Equipment preparation and compatibility testing
The first step to wireless printing is to check the basic specifications of your network. Model L355 supports the standard IEEE 802.11b/g/n, meaning it's compatible with most home routers operating at 2.4 GHz. It's important to note that this printer doesn't support 5 GHz networks, so if your router is dual-band, make sure your phone is connected to the 2.4 GHz network.
Check the lights on the printer control panel. The horizontal bars indicating the Wi-Fi signal strength should either blink (searching or setting mode) or be solid (successful connection). If the lights are unresponsive, the wireless module may be disabled by software or the network settings may need to be reset to factory defaults.
For users on complex corporate networks or providers with specific requirements, knowledge of the encryption type may be required. Epson L355 supports security protocols WEP, WPA-PSK (TKIP) And WPA2-PSK (AES)Using legacy WEP is not recommended due to its poor security, but in rare cases it may be the only way to connect an older device to a guest network.
⚠️ Note: If you're using a router with the "Client Isolation" or "Guest Network" feature, the printer and phone may not be able to see each other even when on the same Wi-Fi network. To print, you must disable this feature in your router settings.
Resetting the Epson L355 printer's network settings
If the device was previously used with a different router or the setup was unsuccessful, you need to clear the saved profiles. This ensures that the printer will start searching for a new connection rather than attempting to connect to a non-existent network. The reset procedure is performed using a combination of buttons on the front panel of the device.
Press and hold the network button (Wi-Fi) and the power button (colored diamond) for a few seconds. The Wi-Fi and Eco lights should flash simultaneously. Then release the buttons. The printer will reboot the network module, and the lights will begin flashing alternately, indicating it is ready for a new setup.
☑️ Preparing for a factory reset
In some cases, especially after updating firmware or changing ISPs, a hard reset may be necessary. To do this, hold the Wi-Fi button for about 10-15 seconds until all the indicators light up. This will reset the network settings to factory defaults but will not affect the CISS settings or page counters.
Setup via the Epson iPrint app (Android and iOS)
The most versatile and functional way to manage printing is the official application Epson iPrintIt's available in the Google Play Store and the Apple App Store. Once installed and launched, the app will automatically scan your local network for compatible devices. If the printer is already connected to the same Wi-Fi network as your phone, it will appear in the list of available devices.
If the printer isn't found, the app will prompt you to set up a wireless connection. Select your network from the list and enter the password. At this point, the phone transfers the router credentials directly to the printer. For successful data transfer, Android devices may request location access permission, as modern OS versions require it to scan for Wi-Fi networks.
| Function | Epson iPrint | Standard Printing Service | Third-party applications |
|---|---|---|---|
| Photo printing | Yes (with editing) | Yes | Depends on the application |
| Scanner | Yes | No | Often paid |
| Ink monitoring | Yes (detailed) | Base | No |
| Printing from the cloud | Yes | No | Rarely |
Once successfully connected, the app will allow you to not only print, but also scan documents, save them as PDF or JPEG, and check the status of consumables. Application interface It's intuitive: select a file, click Print, adjust the paper size and quality, and then confirm.
Using Wi-Fi Protected Setup (WPS) technology
For those who do not want to enter passwords manually or have problems entering special characters on a mobile device, there is a technology WPSThis method allows you to connect Epson L355 To connect to your router with a simple press of a button. However, this method only works if your router has a physical WPS button or supports this feature in software.
Press the WPS button on the router. Within two minutes, press and hold the Wi-Fi button on the printer until the Wi-Fi and Wi-Fi Direct (if available) lights start blinking. The printer will automatically receive the SSID and encryption key from the router. Once setup is complete, the Wi-Fi light on the printer will turn solid.
⚠️ Caution: The WPS method is considered less secure because it facilitates unauthorized access to the network through physical contact with the router. Use it only in a trusted home environment.
If automatic connection doesn't occur, check if WPS is enabled in the router's web interface. Some providers disable this feature by default for security reasons. Also, make sure you haven't exceeded the time limit: if more than two minutes have passed since you pressed the button on the router, you'll have to repeat the process.
What to do if there is no WPS button on the router?
In this case, you can try activating WPS through the router's web interface (usually at 192.168.0.1 or 192.168.1.1). Find the Wireless or Wi-Fi Settings section and press the virtual WPS button, then immediately start searching for the printer.
Printing via standard Android and iOS services
Modern smartphones have built-in printing capabilities, allowing you to send documents without installing additional apps. On Apple devices, this technology is called AirPrint. To print, simply open a document or photo, click the "Share" button, select "Print," and specify Epson L355 in the printer list. There's only one condition: the devices must be on the same network.
Android users can also use the system printing service. Depending on the OS version and smartphone manufacturer, the path may vary: Settings → Connections → Printing Or via the "Share" → "Print" menu. The system will automatically detect the printer on the network if it's configured correctly.
For Android devices that do not support printing natively, you may need to install a plugin. Epson Print Service PluginThis plugin integrates into the system and allows printing from any app that supports the standard Android print service. The plugin is automatically updated via Google Play, ensuring compatibility with new OS versions.
Solving common connection problems
Despite the simplicity of setup, users often encounter a situation where the phone "doesn't see" the printer. One of the most common causes is the router's split frequency range. If the router broadcasts two networks with the same name (SSID) but different frequencies (2.4 and 5 GHz), and the phone is connected to 5 GHz and the printer to 2.4 GHz, they may not detect each other due to routing issues.
Another problem is the DHCP setup. Printer L355 It's advisable to assign a static IP address in your router settings so it doesn't change after each reboot. If the IP address changes, your computer or phone may continue to search for the printer at the old address. You can reserve an address in your router's LAN settings by binding the IP address to the printer's MAC address.
Firewalls and antivirus software on the computer used for initial setup may also be blocking network discovery. Try temporarily disabling the firewall or adding an exception for the printer's IP address. Also, check if "Guest Network" mode is enabled on the router for the device you're printing from.
Why won't my Epson L355 printer connect to Wi-Fi?
There could be several reasons: an incorrect Wi-Fi password, incompatible encryption standards (for example, the router only uses WPA3, while the printer supports up to WPA2), a weak signal, or an overflowing router network connection buffer. Try rebooting the router and printer, and reducing the distance between them.
Is it possible to connect Epson L355 without a router?
No, the L355 model does not support Wi-Fi Direct (printing directly from a phone without a router). A wireless access point (router) to which both the phone and printer are connected is required.
How to find out the IP address of a printer?
To get a network report, press and hold the network button (i) on the printer's control panel for a few seconds until the Wi-Fi light turns on. Then press the black and white print button. The printer will generate a report showing the current IP address.
