How to Connect an HP DeskJet 3755 to WiFi

The HP DeskJet 3755 is a compact all-in-one printer designed with wireless printing in mind — but getting it connected to your home or office WiFi network isn't always as straightforward as it looks. Whether you're setting it up for the first time or reconnecting after a network change, there are several paths available, and the right one depends on your specific devices, operating system, and network configuration.

Why WiFi Setup Matters for This Printer

The DeskJet 3755 doesn't have an ethernet port. That means wireless connectivity is its only network option. If the WiFi connection isn't established correctly, the printer won't be discoverable by your phone, tablet, laptop, or desktop — even if those devices are on the same network. Understanding the setup process properly saves a lot of troubleshooting time later.

The Three Main Methods for Connecting the HP DeskJet 3755 to WiFi

1. HP Smart App Setup (Recommended for Most Users)

HP's own HP Smart app — available for Windows, macOS, Android, and iOS — is the most guided approach. Here's the general flow:

• Download and open the HP Smart app on your device
• Select "Set Up a New Printer"
• Follow the on-screen prompts, which will walk you through connecting the printer to your WiFi network
• The app communicates directly with the printer during setup, sending your network credentials securely

This method works well when your smartphone or computer is already connected to the WiFi network you want the printer to join. The app essentially acts as a bridge during the initial handshake.

2. Wireless Setup Wizard (Via Printer Control Panel)

The DeskJet 3755 has a small control panel with a touchscreen. You can initiate WiFi setup directly from the printer:

• On the printer's screen, tap the Wireless icon (the signal bar icon)
• Open Wireless Settings and select Wireless Setup Wizard
• The printer scans for available networks
• Select your network name (SSID) and enter your WiFi password

This method is useful if you prefer not to use the HP Smart app or if you're on a platform where app access is limited. One important note: the DeskJet 3755 only supports 2.4 GHz WiFi networks, not 5 GHz. If your router broadcasts both bands under the same name, the printer should connect to 2.4 GHz automatically — but some routers keep them separate. If setup fails, confirming you're selecting the correct band matters.

3. WiFi Protected Setup (WPS)

If your router has a WPS button, this is the fastest method:

• Press and hold the Wireless button on the printer for about three seconds until the wireless light starts blinking
• Within two minutes, press the WPS button on your router
• The printer and router negotiate the connection automatically — no password entry required

WPS is convenient but worth understanding: it bypasses manual credential entry by using a push-button or PIN-based exchange. Some network administrators disable WPS due to known security vulnerabilities, so this option isn't always available.

Key Variables That Affect Your Setup Experience

Not every setup goes smoothly on the first attempt. Several factors shape the outcome: 🔧

Restoring or Troubleshooting an Existing Connection

If the printer was previously connected but stopped working — after a router change, password update, or internet outage — the most reliable fix is a network reset on the printer itself:

• Go to Settings on the printer's control panel
• Navigate to Wireless Settings → Restore Network Settings
• This clears the stored network credentials and lets you start fresh

After the reset, run through the Wireless Setup Wizard or HP Smart app again. This is often faster than trying to troubleshoot why a previous connection broke.

Printing Without a Router: HP Wireless Direct

The DeskJet 3755 supports HP Wireless Direct, which creates a small, private WiFi signal from the printer itself. Devices connect to this signal directly — no router involved. This is useful in situations where:

• You're in a location without a WiFi network
• You need to print from a guest device without giving it network access
• You're troubleshooting whether a network issue is causing your connection problems

HP Wireless Direct is not a replacement for standard WiFi setup in a home or office environment, since only one device can typically print at a time, and the printer isn't accessible from other rooms or devices simultaneously.

Drivers, Software, and Operating System Compatibility

Once the printer is on your network, your computer still needs to recognize it. On Windows 10 and 11, the HP DeskJet 3755 is often detected automatically via Windows Update's built-in driver database. On macOS, Apple's AirPrint support handles basic printing without additional driver installation.

For full functionality — scanning, ink level monitoring, firmware updates — the HP Smart app or HP's full feature driver package provides more control. The version of your OS matters here: older operating systems may require manually downloading drivers from HP's support pages. 🖨️

The Setup Path Isn't One-Size-Fits-All

The steps above cover the main routes, but how smoothly each one works depends on details specific to your environment: your router model, how your network is configured, what device you're printing from, and whether any security software is running. A setup that works instantly for one household can require several extra steps in another — not because anything is broken, but because the variables at play are different.

Understanding which method matches your situation, and knowing which variables to check when something doesn't connect, puts you in a much better position than following generic steps and hoping for the best. 📶
