Connecting Your HP Deskjet 3755 to Wi-Fi: A Definitive Guide

Connecting your HP Deskjet 3755 to your Wi-Fi network is a surprisingly straightforward process that opens the door to convenient wireless printing from all your devices. You can accomplish this using the HP Smart app, or via Wireless Direct and the Embedded Web Server (EWS) if needed. Here’s a detailed, step-by-step guide to get you started.

Method 1: Using the HP Smart App (Recommended)

The HP Smart app provides the easiest and most intuitive way to connect your Deskjet 3755 to Wi-Fi. It streamlines the process and offers guided instructions.

Step 1: Download and Install the HP Smart App

First, you’ll need the HP Smart app. It’s available for free on various platforms:

Smartphones and Tablets (Android/iOS): Search for “HP Smart” in the Google Play Store or Apple App Store and download the app.
Computers (Windows/macOS): You can download it from the Microsoft Store or the HP website (search “HP Smart download”).

Step 2: Prepare Your Printer

Make sure your HP Deskjet 3755 is powered on. Place it close to your Wi-Fi router during the initial setup for a stronger signal. Also, ensure you have the Wi-Fi password readily available.

Step 3: Launch the HP Smart App and Add Your Printer

Open the HP Smart app on your device. If it’s your first time using the app, you’ll need to create an HP account or sign in to an existing one. Once logged in, the app should automatically detect your printer if it’s in setup mode (a blinking wireless light is a good indication). If not, click the “+” button or “Add Printer” option.

Step 4: Follow the On-Screen Instructions

The app will guide you through the setup process. It will typically ask you to:

Select your Wi-Fi network from the list of available networks.
Enter your Wi-Fi password. Double-check for typos to avoid connection errors.
Wait for the printer to connect. The app will display progress messages.

Step 5: Complete the Setup

Once the connection is established, the HP Smart app will prompt you to configure additional settings, such as:

Enabling Web Services: This allows you to use features like ePrint and HP Instant Ink (if applicable).
Naming your printer: Choose a descriptive name to easily identify it on your network.
Updating the printer firmware: Keeping your printer’s firmware up-to-date ensures optimal performance and security.

After completing these steps, your HP Deskjet 3755 should be successfully connected to your Wi-Fi network. You can now print wirelessly from any device connected to the same network.

Method 2: Using Wireless Direct and the Embedded Web Server (EWS)

If the HP Smart app doesn’t work, or you prefer a more direct approach, you can use Wireless Direct and the Embedded Web Server (EWS).

Step 1: Enable Wireless Direct on Your Printer

Wireless Direct creates a direct Wi-Fi connection between your computer or mobile device and the printer, without needing a router.

Press and hold the Wireless button on your printer until the Wireless Direct light starts blinking. The location of this button can vary slightly but is typically marked with a wireless icon.
Once the light is blinking, the printer is broadcasting its Wireless Direct network.

Step 2: Connect to the Printer’s Wireless Direct Network

On your computer or mobile device:

Go to your Wi-Fi settings and look for a network name that includes “DIRECT-” followed by your printer’s model number.
Select the printer’s Wireless Direct network and connect to it.
If prompted, the default Wireless Direct password is usually “12345678” or “00000000”. Check your printer’s documentation if neither works.

Step 3: Access the Embedded Web Server (EWS)

Once connected to the printer’s Wireless Direct network:

Open a web browser on your computer or mobile device.
Type the printer’s IP address into the address bar. To find this IP address, print a network configuration page from the printer. Typically, hold the Information button until a report prints. The Wireless Direct IP address will be on this page. Alternatively, you can usually find it in the printer’s control panel menu under network settings.
The Embedded Web Server (EWS) page will load. This is the printer’s internal configuration interface.

Step 4: Configure Wi-Fi Settings in the EWS

In the EWS, navigate to the Network or Wireless settings. The exact wording may vary depending on the printer’s firmware version.
Look for the Wireless Setup Wizard or a similar option to connect to your Wi-Fi network.
Select your Wi-Fi network from the list of available networks and enter your Wi-Fi password.
Click Apply or Save to save the changes.

Step 5: Verify the Connection

The printer will attempt to connect to your Wi-Fi network. Once connected, the Wireless light on the printer should be solid (not blinking). You can also check the printer’s control panel menu or print a network configuration page to confirm the connection.

You’ll now need to reconnect your computer or mobile device back to your usual Wi-Fi network to print.

Troubleshooting Tips

Ensure your Wi-Fi router is working correctly: Restart your router and modem if you’re experiencing connection issues.
Check your Wi-Fi password: Even a small typo can prevent the printer from connecting.
Bring the printer closer to the router: A weak Wi-Fi signal can cause connection problems.
Update the printer’s firmware: Outdated firmware can sometimes cause compatibility issues.
Restart the printer: A simple restart can often resolve temporary glitches.
