How to Easily Connect Your HP DeskJet 3755 to Wi-Fi

 


The HP DeskJet 3755 is a compact all-in-one printer known for its portability and efficient printing, scanning, and copying capabilities. One of its key features is wireless printing, which allows you to print from any device connected to the same Wi-Fi network. If you’ve recently purchased the HP DeskJet 3755 or are facing difficulties connecting it to your Wi-Fi, this guide will walk you through the entire process with easy-to-follow steps.

We will also cover solutions to some common issues like HP printer offline default password concerns, and give you a glimpse into the HP OfficeJet Pro 6978 setup in case you're curious about other HP models.

Step 1: Preparing the Printer

Before connecting your HP DeskJet 3755 to Wi-Fi, ensure the following:

  1. Power On the Printer: Ensure that your printer is properly plugged into a power outlet and turned on.
  2. Check for Ink Cartridges: Verify that the ink cartridges are installed, and there is paper loaded into the tray.
  3. Factory Reset (if needed): If your printer has been previously connected to another network, you may want to reset it to avoid connection issues. To do so, press and hold the "Cancel" and "Wireless" buttons simultaneously for 3 seconds. The wireless light will blink to indicate that the settings have been restored.

Step 2: Download the HP Smart App

To easily connect HP DeskJet 3755 to Wi-Fi the HP Smart App is highly recommended. The app helps in managing your printer’s settings and functions, including wireless connectivity.

  1. Download and Install HP Smart App:

    • Visit the App Store (iOS) or Google Play Store (Android) and search for the HP Smart app. Alternatively, if you’re using a Windows PC or Mac, you can download it from the HP website.
    • Once installed, open the app and create or log in to your HP account.

  2. Connect the Printer to Wi-Fi:

    • With the app open, ensure your smartphone or computer is connected to the same Wi-Fi network you want the printer to use.
    • On the app, click “Set Up a New Printer” and select “HP DeskJet 3755” from the list of available printers.
    • Follow the on-screen instructions to connect the printer to your Wi-Fi network.
    • If prompted for a password, enter the default Wi-Fi password for your router, which can typically be found on the router's label or in your router's manual.

Step 3: Manually Connect Using Wi-Fi Protected Setup (WPS)

If you prefer not to use the HP Smart app, you can connect your HP DeskJet 3755 to Wi-Fi using Wi-Fi Protected Setup (WPS). This method is useful if your router supports WPS.

  1. Activate WPS on Your Printer:

    • Press and hold the Wireless button on your HP DeskJet 3755 for three seconds until the wireless light starts blinking.

  2. Activate WPS on Your Router:

    • Locate the WPS button on your router (usually found on the back or side).
    • Press and hold the WPS button for several seconds until the router starts searching for devices.

  3. Connection Confirmation:

    • After a few moments, your HP DeskJet 3755 will automatically connect to the Wi-Fi network. You can confirm this by checking if the wireless light on the printer stops blinking and remains solid.

Step 4: Resolving “HP Printer Offline” Error

Once connected, you may still experience issues like the “HP Printer Offline” message when trying to print. This can be frustrating, but it’s often easy to fix.

  1. Check Wi-Fi Connectivity: Ensure your printer is still connected to the Wi-Fi network. If the wireless light on the printer is blinking, it means the connection has been lost.
  2. Restart Devices: Restart your printer, router, and computer or mobile device to refresh the connection.
  3. Set Printer as Default: On your computer, go to Control Panel > Devices and Printers (or Printers & Scanners on Mac). Right-click on your HP DeskJet 3755 and select “Set as default printer.”
  4. Disable Offline Mode: If the printer is set to work offline, you’ll need to change this setting. In Devices and Printers, right-click on the printer, and ensure that “Use Printer Offline” is unchecked.

Step 5: Finding the Default Password for HP DeskJet 3755

If the printer asks for a password during setup, you may need the default password. HP DeskJet 3755 does not have a default password for general use, but you might be prompted for the Wi-Fi Direct password.

To find the Wi-Fi Direct password:

  1. Press the Information button on the printer control panel. This will print an information page.
  2. Locate the Wi-Fi Direct section on the page to find the password listed there. This password can be used to connect your devices directly to the printer without needing a Wi-Fi network.

Step 6: General Troubleshooting

  • Reinstall Drivers: If you’re having trouble with the connection, consider uninstalling and reinstalling the printer drivers from the HP website. This ensures you have the latest version.
  • Check Firewall Settings: Sometimes, firewalls or antivirus software can block the connection between your printer and computer. Temporarily disabling them might help resolve connection issues.
  • Contact HP Support: If all else fails, reach out to HP’s customer support for further assistance.

Bonus: HP OfficeJet Pro 6978 Setup Overview

If you're considering upgrading or exploring different HP models, the HP OfficeJet Pro 6978 setup is another popular wireless printer with additional features like automatic two-sided printing and a larger paper tray.

Here’s a quick look at the HP OfficeJet Pro 6978 Setup:

  1. Power On and Load Paper: Like the DeskJet 3755, begin by powering on the printer and loading paper.
  2. Install Cartridges: Ensure the ink cartridges are installed correctly.
  3. Download HP Smart App: This model also supports the HP Smart App for seamless wireless setup.
  4. Connect to Wi-Fi: You can connect using either the HP Smart App or the manual WPS method described earlier.

Conclusion:

Connecting your HP DeskJet 3755 to Wi-Fi is straightforward, whether you use the HP Smart app or WPS method. Once connected, ensure your printer remains online by troubleshooting any “HP Printer Offline” errors and managing your network settings. By following this guide, you’ll have your printer up and running wirelessly in no time.
