Mobile printing has long ceased to be a novelty and has become a standard feature used by smartphone owners to instantly obtain paper copies of documents or photographs. Epson L3150 MFP is one of the most popular models in this segment due to its reliability and the presence of a built-in module Wi-Fi, eliminating unnecessary wires. However, despite its claimed simplicity, initial setup of the connection between the phone and printer often raises questions among users, especially when it comes to specific connection scenarios.
In this article, we'll take a detailed look at all the possible ways to establish a wireless connection between your gadget and a printer. You'll learn about the intricacies of the app's operation. Epson iPrint, you will understand the difference between standard infrastructure mode and direct connection Wi-Fi Direct, and also learn how to troubleshoot common errors that occur during network configuration.
Before you begin software setup, make sure the printer itself is physically ready for use. This includes installing the ink cartridges, loading paper into the tray, and connecting the device to a power source. The Wi-Fi indicator on the control panel should flash green, indicating that the module is ready to search for a network. If the indicator light is constantly on or does not light at all, you will need to reset the network settings of the printer itself.
Preparing the device and resetting network settings
The first step in setting up wireless printing is to prepare the printer's network module for the new configuration. It often happens that the device "remembers" the old router settings or is in standby mode, which prevents the phone from detecting it. First, make sure that MFP turned on and is within the range of your wireless router's signal.
If you previously set up the printer from another computer or router, or simply changed the Wi-Fi password, you need to reset the network settings. To do this, locate the Wi-Fi button (the smartphone icon) on the Epson L3150 control panel. Press and hold it together with the Cancel button (the triangle in a circle) for a few seconds until the lights start flashing. This will reset the network settings to their factory defaults.
⚠️ Attention: After resetting your Wi-Fi settings, all previously saved passwords and network configurations will be deleted from the printer's memory. You will need to re-enter your connection information to your router.
After a successful reset, the Wi-Fi indicator and Wi-Fi Direct indicator should begin blinking. This means the device has entered setup mode and is now actively searching for available commands or attempting to create its own access point for initial configuration. Do not turn off the printer until all setup procedures are complete, as this may damage the device's internal file system.
What to do if the indicators do not blink after reset?
If the LEDs don't change their blinking pattern after holding the buttons, try unplugging the printer for 10-15 seconds. Then plug it back in and repeat the reset procedure. In rare cases, holding the buttons for a longer period of time—up to 10 seconds—may require a longer press.
Using the Epson iPrint app for Android and iOS
The most functional and convenient way to manage printing is the official application Epson iPrintIt is available for free download in stores. Google Play And App StoreThis software not only allows you to print documents and photos, but also scan images directly from your phone and check the ink levels in your CISS.
The setup process through the app is as automated as possible. After installation, launch Epson iPrint On a smartphone connected to the same Wi-Fi network to which you plan to connect the printer. The app will automatically search for available devices on the local network. If the printer isn't yet connected to the router, the app will prompt you to set up a Wi-Fi connection.
During setup, you'll be asked to select your home router from a list and enter its password. It's important that location services (for Android) and local network access permissions are enabled on your phone at this point. Without these permissions, the operating system may block the transfer of the Wi-Fi password to the printer for security reasons.

Setting up Wi-Fi Direct printing without a router
One of the key features of the L3150 model is its support for technology Wi-Fi DirectThis mode allows you to print directly between your phone and printer, bypassing the wireless router. This is especially useful when the router is unavailable, located far away, or when you're visiting someone and can't connect to their network.

| Parameter | Standard Wi-Fi | Wi-Fi Direct |
|---|---|---|
| Presence of a router | Required | Not required |
| Internet access | Yes (via router) | No (print only) |
| Transfer speed | Depends on the router | Direct connection |
| Number of users | Multiplayer | Limited (usually up to 4) |
Printing documents and photos from different applications
Once successfully connected using one of the methods described above, printing is a breeze. Open the document, photo, or web page you want to print. From the app menu (usually the three dots or the "Share" button), select "Seal" or Print.
The system will prompt you to select a printer. If you are using Android, you may need to select a plugin. Epson Print Enabler, which is often installed automatically or available in the Play Market. iOS (iPhone/iPad) users are more fortunate – the technology AirPrint built into the system and no additional drivers are needed.
In the preview window that opens, you can adjust the settings: select the paper size (usually A4), orientation (portrait or landscape), number of copies, and paper type. For photos, it's important to select the correct format, such as 10x15 cm, and ensure the printer is loaded with photo paper.
- 📄 For text documents, choose black and white printing to save color ink.
- 🖼️ For photos, set the highest quality and select the paper type "Epson Matte" or "Glossy".
- 📑 For multi-page documents, check the page order to ensure they are not printed in reverse order.

Solving common connection problems
Despite the streamlined processes, users may encounter situations where the phone "doesn't see" the printer or the connection constantly drops. One common cause is the router operating in two bands (2.4 GHz and 5 GHz). The Wi-Fi module in the Epson L3150 only supports the 2.4 GHz and 5 GHz bands. 2.4 GHzIf your router separates networks or hides one of them, your phone may try to connect via an unsupported band.
Problems can also arise due to router security settings. Some providers or network administrators implement MAC address filtering or use complex corporate encryption protocols that budget home printers don't support. It's recommended to use standard encryption on home networks. WPA2-PSK.
⚠️ Attention: If you're using a guest Wi-Fi network, make sure AP Isolation is disabled in your router settings. Otherwise, your phone and printer won't be able to see each other, even if they're on the same network.
Another important point is firmware updates. The manufacturer periodically releases updates that improve connection stability. You can check for a new version through the app. Epson iPrint in the device information section.
