Wireless printing of documents and photos is a standard in modern office and home use, eliminating unnecessary wires and allowing you to manage tasks from any device in the home. Model Epson L355Despite its age, the printer remains popular due to its continuous ink supply system and reliability, but its initial setup via Wi-Fi often raises questions for users accustomed to more modern interfaces.
Integrating this MFP into your home network requires a sequential process, as the device doesn't have a full-screen display for password entry and relies on software utilities or button combinations. In this article, we'll cover every setup step in detail, from preparing the hardware to troubleshooting common errors, so you can start printing without delays or unnecessary frustration.
It's important to understand that the success of the operation depends not only on the printer itself, but also on the correct settings of your router and computer operating system. We'll cover methods for Windows and mobile devices, ensuring the instructions are universal for any use case.
Preparatory stage and equipment requirements
Before you begin setup, you need to make sure your equipment is ready to work wirelessly. Device Epson L355 supports Wi-Fi 802.11 b/g/n standards, which means it is compatible with the vast majority of home routers, but there are nuances with frequency ranges.
It is critical to know that this printer operates exclusively within the range 2.4 GHz and doesn't see networks that only operate in 5 GHz mode. If your router broadcasts a single network (Smart Connect) or only 5 GHz, you'll need to go into the router settings and enable a guest network or a separate SSID for the 2.4 GHz band.
- 📶 Make sure your laptop or smartphone is connected to the same Wi-Fi network to which you plan to connect the printer.
- 🔌 The printer must be turned on and filled with ink, the indicators must be on steadily and not blinking.
- 📄 Download the full package of drivers and utilities from the manufacturer's official website in advance to avoid interruptions in the file search process.
- 🔐 Please have your Wi-Fi network password ready as you will need to enter it into the software.
It's also worth checking if MAC address filtering is enabled on your router, which could block new devices from connecting. Your printer's MAC address can be found by printing a network status report, but we'll cover that in the diagnostics section.
⚠️ Note: If you are using a corporate network or a provider network with web page authentication (Captive Portal), direct printer connection may not be possible without the help of a system administrator.
WPS method: quick connection without entering a password
The easiest way that is often overlooked by users is the use of technology WPS (Wi-Fi Protected Setup). This method allows you to connect your printer to your router with the simple press of a button, eliminating the need to manually enter a complex password on your computer keyboard.
To implement this method, your router must have a physical WPS button or a corresponding function in the web interface. On the printer Epson L355 There is also a Wi-Fi button, which, when combined with the start button, allows you to activate the network search mode.
☑️ Pre-launch WPS check
The process takes no more than two minutes. First, press and hold the Wi-Fi button on the printer until the Wi-Fi and Wi-Fi Direct lights begin flashing alternately. Then, press the WPS button on the router.
The device will automatically exchange encryption keys. The Wi-Fi indicator on the printer should turn solid green, indicating a successful connection. If the indicator is blinking green, data is being transferred, and if it is orange, an error has occurred.
Setup via USB cable and software
If WPS is unavailable or your router doesn't support it, the most reliable method is to use the installation disc or downloaded software and then switch to wireless mode. This method ensures that all necessary system components are installed.
Run the installation file Epson Installer On a computer connected to Wi-Fi. Select your model from the list and agree to the license agreement. When prompted for a connection type, select "Wireless" or "Wi-Fi."
At a certain point, the installer will ask you to temporarily connect the printer to your computer via a USB cable. This is necessary to transfer the network settings (SSID and password) directly to the printing module.
1. Connect the USB cable.2. Wait for the device to be detected.
3. Select your network from the list.
4. Enter the Wi-Fi password.
5. Disconnect the USB cable according to the instructions.
After transferring the settings, the program will prompt you to disconnect the USB cable. The printer will automatically reconnect to the network, and the computer will detect it as a network device. At this point, it's important not to turn off the printer's power until the indicators stabilize.
| Indicator | State | Meaning |
|---|---|---|
| Wi-Fi (green) | It's on constantly | Successful connection to the network |
| Wi-Fi (green) | Flashing | Obtaining an IP address or transmitting data |
| Wi-Fi (orange) | It's on constantly | Wi-Fi Direct mode is active |
| Wi-Fi (orange) | Flashing | Connection error or searching for network |
What should I do if my computer doesn't see my printer after setup?
If the printer doesn't appear in the list of devices after disconnecting the USB cable, check your firewall. Sometimes antivirus programs block the detection of network printers. Try temporarily disabling the firewall or adding an exception for Epson services. Also, make sure your network settings are set to "Private Network" and not "Public."
Using Wi-Fi Direct to print from your phone
Technology Wi-Fi Direct Allows you to connect mobile devices directly to the printer without using a router. This is ideal for quickly printing photos from your smartphone when your main router is unavailable or overloaded.
To activate this mode on Epson L355, press and hold the phone button (or the Wi-Fi button if your phone doesn't have a dedicated button) until the orange Wi-Fi indicator lights up. The printer will create its own access point.
On your smartphone, you need to open the list of available Wi-Fi networks and find the network with a name starting with DIRECT-xx-EPSONThe default password is usually found on a sticker on the device or in the user manual, often 12345678.
- 📱 Open the app Epson iPrint on a smartphone.
- 🔗 Select your printer from the list of available devices.
- 📄 Select a document or photo to print.
- ✅ Click the print button and wait for it to complete.
Please note that in Wi-Fi Direct mode, data transfer speeds may be lower, and the phone itself may lose internet access if it does not support dual Wi-Fi operation. After finishing printing, it is recommended to switch back to the main network.
⚠️ Important: When connecting via Wi-Fi Direct, make sure you haven't confused your printer's network with a neighbor's device with a similar name. Always check the last digits of the MAC address in the network name.
Manual IP address configuration and static route
In complex network environments where the router's DHCP server is unstable or changes device addresses, it is recommended to assign the printer static IP addressThis will prevent situations where the computer "loses" the printer after rebooting the router.
First, you need to find out the printer's current IP address. You can do this by printing a network status report: press and hold the network button (the antenna icon) for 7-10 seconds. In the report, look for the line IP Address.
Access the printer's web interface by entering this address in your browser. Go to the section Network -> TCP/IPHere you can switch the mode from Auto (DHCP) on Manual and enter the address that matches the subnet of your router (for example, if the router 192.168.1.1, give it to the printer 192.168.1.200).
After changing the IP address, you need to update the printer port in the Windows operating system. Go to "Devices and Printers," select your Epson's properties, go to the "Ports" tab, and add a new port. Standard TCP/IP Port with a new address.
Diagnosis and solution of typical problems
Even if you follow the instructions exactly, problems may still occur. Often, the problem lies not with the printer itself, but with the router's security settings or operating system drivers. First, try rebooting the entire chain: the router, the computer, and the printer.
If the printer does not see the network, check if the SSID (network name) is hidden. Epson L355 Hidden networks may not appear in the list when configured manually. Also, make sure AP client isolation isn't enabled on your router, which prevents devices on the same network from "seeing" each other.
If you're having driver issues on Windows 10 or 11, try removing the device completely via Settings -> Devices -> Printers & Scanners. Then, use the "Add a printer or scanner" button and select "The printer I want is missing" to manually set it by IP address.
If all else fails, reset the printer's network settings to factory defaults. To do this, turn off the printer, hold down the network button and the cancel (triangle) button, then turn on the printer while holding them. The lights will flash, confirming the reset.
