In this article we will look at all stages of connection — from preparing the router to installing drivers on your PC. We'll pay special attention to common errors (for example, when a printer doesn't see the network or the computer can't detect it), as well as security nuances. If you're using Windows 10/11 or macOS, the instructions will be universal, but taking into account the specifics of each system. For owners SCX-3400W (version with Wi-Fi module) and SCX-3400 (requires external adapter) separate recommendations are provided.

What to do if the driver is not installed?

If the installer gives an error, try:

1. Run it as administrator (right-click → "Run as administrator").

2. Temporarily disable your antivirus (it may block the installation of drivers).

• 📥 Update printer firmware via Samsung Easy Printer Manager.
• 🔄 Restart both the printer and the computer.

6. Additional features: scanning and security

Besides printing, Samsung SCX-3400 Supports network scanning. To configure this feature:

1. Install the program Samsung Easy Document Creator (comes with drivers).

2. Run it and select Network scanning.

3. Enter the printer's IP address and follow the wizard's instructions.

For network security, it is recommended:

• 🔒 Change the default password for the router's admin panel.
• 📡 Disable guest Wi-Fi access.
• 🖥️ Assign a static IP address to the printer in the DHCP settings (so that it doesn't change when you reboot the router).

If you use a printer in your office, consider setting it up VLAN to isolate print traffic from the main network. This will protect data from interception. It's also useful to disable protocols FTP And Telnet in the printer settings (if enabled by default), as they are vulnerable to attack.

7. Alternative connection methods

If connecting via Wi-Fi fails, consider alternative options:

• 🔌 USB cable — reliable, but limits mobility. Suitable for a permanent workstation.
• 🌐 Ethernet - if the printer has a port LAN (V SCX-3400 there isn't one, but you can use a print server).
• 📱 Mobile printing — via the app Samsung Mobile Print (requires Wi-Fi Direct).

To connect via print server (For example, TP-Link TL-PS110U):

1. Connect the print server to the printer's USB port and to the router via Ethernet.

2. Configure the print server through its web interface (usually 192.168.0.10).

3. Install the driver on your computer by specifying the IP address of the print server.

The advantage of this method is stability, since the connection is wired. The disadvantage is the additional equipment costs. If mobility is a priority, it's better to configure the printer's native Wi-Fi module.
