How to Connect an Epson L355 Printer to an iPhone via Wi-Fi: A Complete Guide with Troubleshooting

Wireless printing with iPhone to the printer Epson L355 It seems like a simple task—until you encounter connection errors, an "invisible" device on the network, or driver issues. This model, despite its popularity among home and office users, has a number of nuances when setting up a Wi-Fi connection with devices on iOS. Unlike Android, where standard protocols are often sufficient, Apple uses a proprietary AirPrint protocol., which does not always interact correctly with third-party printers.

In this guide, we will cover not only the basic connection procedure, but also common mistakes (for example, when the printer is not displayed in the list of devices or printing "freezes" at the sending stage), as well as alternative methods - from using the proprietary application Epson iPrint to manual configuration via IP address. We will pay special attention compatibility with the latest versions of iOS (17+), where Apple has tightened security requirements for network devices.

If you have already tried to connect and received an error like "Unable to find printer" or "The connection was interrupted."Don't rush to reset your printer. In 80% of cases, the problem can be resolved by adjusting the router settings or updating the firmware. Epson L355Let's start with preparing the equipment - that's half the battle.

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

Before connecting Epson L355 With iPhone, you need to make sure the printer itself is ready for wireless operation. Many users skip this step, which later leads to errors like "The Wi-Fi module is disabled" or "No response from the device".

The first thing to do is Check the physical condition of the printer:

  • 🔌 Make sure the printer is plugged in and the power indicator is green (not flashing red - this indicates an error).
  • 📡 Click the button Wi-Fi On the control panel (to the right of the display)—the light next to it should turn blue. If it's blinking orange, the Wi-Fi module is disabled or faulty.
  • 📄 Check that there is paper in the tray (the printer may block network functions if there is no media).

Next, go to the printer menu:

  1. Click the button Settings (gear) on the panel.
  2. Select Net → Setting up Wi-Fi → Access point.
  3. Remember the network name (SSID) and password that the printer generated automatically (usually a combination like DIRECT-xx-Epson_L355).

Important: Epson L355 supports two Wi-Fi modes:

  • Infrastructure mode — connection via a router (recommended for stable operation).
  • Access point mode (Wi-Fi Direct) — direct connection to the device. Convenient for one-time printing, but can be slow with large data volumes.

2. Configuring the router for a stable connection

If you have chosen to connect via a router (infrastructure mode), router settings may be blocking the connection between iPhone and a printer. This is especially relevant for modern routers with security features, such as WPA3, MAC filtering or Isolation of clients.

Check the following settings in the router admin panel (usually accessible at 192.168.0.1 or 192.168.1.1):

Parameter Recommended value Why is this important?
Security mode WPA2-PSK (AES) Epson L355 does not support WPA3, A TKIP may cause delays.
Channel width 20 MHz (for 2.4 GHz) The printer may not see the network at a width 40 MHz.
Client Isolation (AP Isolation) Disabled Enabled isolation blocks data exchange between devices on the network.
DHCP server On The printer should automatically obtain an IP address.

If your router operates in dual-band mode (2.4 GHz And 5 GHz), printer Epson L355 Only supports 2.4 GHz. Make sure the 2.4 GHz network is enabled and has a unique name (not the same as 5 GHz). Some routers (e.g., TP-Link or ASUS) by default, they combine networks under one SSID - this can cause problems.

How to check what frequency your iPhone is connected to?

Open Settings → Wi-Fi On your iPhone, tap your network name. If the "Router" section shows a channel higher than 14 (e.g., 36, 40), then you're connected to 5 GHz. To print, you'll need to switch to 2.4 GHz.

After changing the router settings Restart both the printer and iPhoneThis will reset the network connection cache and eliminate any possible conflicts.

3. Connecting an iPhone to an Epson L355 printer via Wi-Fi Direct

If the connection via the router failed or you need to print a document urgently, use Wi-Fi Direct modeThis is a direct connection between iPhone and a printer without intermediaries. The downside of this method is that you won't be able to use the internet on your phone while connected.

Step-by-step instructions:

  1. On the printer, press and hold the button Wi-Fi 3 seconds until the indicator starts flashing blue.
  2. On iPhone open Settings → Wi-Fi.
  3. In the list of networks, find the printer network (for example, DIRECT-xx-Epson_L355) and connect to it. The password is indicated on the printer screen or in the manual (usually 12345678 or empty).
  4. Once connected, open a document (photo, PDF, page in Safari) and select the print option.

The printer is on and the Wi-Fi indicator is blinking blue|iPhone is connected to the DIRECT-xx-Epson_L355 network|Wi-Fi settings show "Connected" without an exclamation mark|Test print started
