What Is the HP DeskJet 4155e?

The HP DeskJet 4155e is an all-in-one inkjet printer that prints, scans, and copies. It is built for everyday home use, student work, small business paperwork, and occasional photo or document printing. Its wireless capability is one of its most useful features because it lets multiple devices share one printer without a physical USB connection.

Although the printer can work through a USB cable, most users prefer Wi-Fi because it allows printing from a phone in another room, scanning to a laptop on the couch, or sharing the printer among family members. The setup process is usually simple, but it can feel confusing if your router has unusual settings, if your network uses both 2.4 GHz and 5 GHz bands, or if the printer was previously connected to a different network.

Before You Start: Requirements and Preparation

Before attempting to answer How to Connect Hp4155e to Wifi? in your own home, gather a few details. Having them ready prevents repeated setup attempts and reduces the chance of entering the wrong password.

  • Your Wi-Fi network name, also called the SSID.
  • Your Wi-Fi password, including uppercase letters, lowercase letters, numbers, and symbols.
  • A smartphone, tablet, or computer connected to the same Wi-Fi network you want the printer to use.
  • The printer powered on and placed within a reasonable distance of the router.
  • The latest version of the HP Smart app if you plan to use mobile setup.
  • A USB cable if you choose the wired setup method.

It is also helpful to check whether your router broadcasts a 2.4 GHz network. Many HP printers connect most reliably to 2.4 GHz Wi-Fi. If your router uses a combined network name for both bands, the printer may still connect, but separation into distinct 2.4 GHz and 5 GHz names can make troubleshooting easier.

Place the printer where it will not be blocked by thick walls, metal cabinets, or large appliances. A weak signal can cause slow printing, dropped connections, or failed setup. If possible, keep the printer within one or two rooms of the router.

Method 1: Connect Using WPS

WPS, or Wi-Fi Protected Setup, is the fastest method when your router has a WPS button. It avoids typing the Wi-Fi password into the printer. This method is ideal if you want a quick setup and your router supports WPS.

Step-by-Step WPS Setup

  1. Turn on the HP DeskJet 4155e and make sure it is not printing, scanning, or copying.
  2. Check that the printer is in a ready state. If it is already connected to another network, you may need to reset its network settings first.
  3. Press and hold the Wireless button on the printer for about three seconds. The wireless light should begin blinking, indicating that the printer is in setup mode.
  4. Within two minutes, press the WPS button on your router.
  5. Wait while the printer and router communicate. The wireless light may blink during the process.
  6. When the connection is successful, the wireless light should become solid.
  7. Print a network configuration page or use HP Smart to confirm that the printer has an IP address.

If the light keeps blinking or turns off, the WPS attempt failed. Move the printer closer to the router, restart both devices, and try again. Some routers disable WPS by default for security reasons, so check your router settings if the button does not seem to work.

Method 2: Connect Using the HP Smart App

The HP Smart app is one of the most reliable ways to connect the printer because it guides you through each step and can send your Wi-Fi credentials to the printer. It is available for Android, iOS, Windows, and macOS.

Using HP Smart on a Phone or Tablet

  1. Download and install HP Smart from the Google Play Store or Apple App Store.
  2. Open the app and create or sign in to an HP account if prompted.
  3. Make sure your phone or tablet is connected to the Wi-Fi network you want the printer to use.
  4. Turn on the printer and place it close to your phone or router.
  5. In HP Smart, select the option to add a printer.
  6. Follow the on-screen instructions. The app may ask you to temporarily connect to a printer setup network or use Bluetooth, depending on the device and printer state.
  7. When prompted, enter your Wi-Fi network name and password exactly as they appear on your router.
  8. Wait for the app to confirm that the printer is connected.
  9. Print a test page from the app to verify the connection.

If the app cannot find the printer, restart the printer, close and reopen the app, and ensure that location permissions and local network permissions are enabled. On iOS, local network access is especially important because the app needs permission to discover devices on your Wi-Fi.

Using HP Smart on Windows or macOS

  1. Install HP Smart from the Microsoft Store on Windows or from the Mac App Store on macOS.
  2. Connect your computer to the target Wi-Fi network.
  3. Open HP Smart and choose to add a printer.
  4. Follow the setup wizard. If the printer is already in setup mode, the computer should detect it.
  5. Enter your Wi-Fi credentials when requested.
  6. Complete the HP account and printer registration steps if desired.
  7. Print a test page from your computer.

Desktop setup is especially useful if you want the printer installed as a Windows or macOS printer at the same time. It can also help if mobile app discovery is inconsistent.

Method 3: Connect Using a USB Cable First

If wireless setup keeps failing, a USB connection can provide a stable bridge. You can connect the printer to a computer with a USB cable, install the necessary software, and then configure the wireless settings from the computer.

  1. Connect one end of a compatible USB cable to the printer and the other end to your computer.
  2. Turn on the printer.
  3. On Windows, open Settings, then Bluetooth and devices, then Printers and scanners, and add the printer. On macOS, open System Settings, then Printers and Scanners, and add the printer.
  4. Install any recommended HP software or drivers.
  5. Open HP Smart or the HP printer software and look for wireless setup or network settings.
  6. Select your Wi-Fi network and enter the password.
  7. Wait for confirmation that the wireless connection is active.
  8. Disconnect the USB cable once the printer is successfully connected to Wi-Fi.
  9. Print a test page wirelessly to confirm that the cable is no longer needed.

This method is helpful in environments with poor Wi-Fi signal near the printer or when the printer is not being discovered automatically. It also gives you a fallback if the mobile app is not working.

Method 4: Connect Using HP Software on a Computer

Sometimes the best approach is to use the full HP software package on a computer. This can install drivers, utilities, and network tools that make setup more predictable.

  1. Visit HP’s official support website and search for the HP DeskJet 4155e.
  2. Download the recommended full feature software or HP Smart for your operating system.
  3. Run the installer and follow the prompts.
  4. When asked how the printer is connected, choose wireless setup.
  5. If the installer asks whether the printer is already on the network, select the option that matches your situation.
  6. If the printer is not yet connected, use the installer’s wireless setup tool to select your network and enter the password.
  7. Complete driver installation.
  8. Print a test page from the computer.

This method is especially useful for offices where IT policies, firewalls, or custom network configurations make automatic discovery difficult. It also ensures that scanning features and advanced printer settings are installed correctly.

Connect to a New Router or Changed Password

If your printer was working before but stopped after a router replacement or password change, the printer is likely still trying to use the old network details. You do not necessarily need to reinstall everything, but you do need to update the printer’s wireless settings.

  1. Turn on the printer.
  2. Reset the printer’s network settings if needed. Many HP printers allow this through a button combination or through HP Smart.
  3. Put the printer back into setup mode.
  4. Use WPS, HP Smart, or USB setup to connect it to the new network.
  5. Update the printer on each computer or phone that previously used it. Sometimes the device list still points to the old printer instance.
  6. Remove duplicate printer entries and re-add the printer if necessary.

When changing routers, also check whether the new router uses a different security type. Most modern routers use WPA2 or WPA3. If the router is set to WPA3-only, some older printers may have difficulty connecting. In that case, enabling WPA2/WPA3 mixed mode can improve compatibility.

Print a Test Page and Verify Status

After setup, do not assume the connection is permanent until you test it. A successful test page proves that the printer, router, and device can communicate.

  • From HP Smart, select the printer and choose Print or Print Test Page.
  • From Windows, open Printers and scanners, select the HP DeskJet 4155e, and choose Manage, then Print a test page.
  • From macOS, open System Settings, Printers and Scanners, select the printer, and use the print queue or printer utility options.
  • From a phone, open a document, photo, or PDF and choose Print, then select the HP printer.

You can also print a network configuration page from the printer if supported. This page usually shows the IP address, network name, signal strength, and connection status. Save or note the IP address for future troubleshooting.

Troubleshooting Common Wi-Fi Issues

Even with a good setup process, wireless printing can encounter problems. The following checklist resolves most issues.

Wrong or Expired Password

Wi-Fi passwords are case-sensitive. Check for hidden spaces, confusing characters such as uppercase I and lowercase l, and numbers that look like letters. If you recently changed the password, update it on the printer as well.

2.4 GHz vs. 5 GHz Problems

If your router has separate names for each band, connect the printer to the 2.4 GHz network. If the names are combined, try temporarily separating them in the router settings. This is one of the most common reasons a printer fails to connect even when the password is correct.

Weak Signal or Interference

Move the printer closer to the router during setup. Avoid placing it behind metal, inside cabinets, or near microwaves and cordless phones. After setup, you can move it back if the signal remains strong.

VPN, Firewall, or Security Software

VPNs can block local device discovery. Disable the VPN temporarily while setting up the printer. On computers, firewall settings may block HP software; allow HP applications through the firewall if prompted.

Duplicate Printer Entries

After multiple setup attempts, your computer may have several entries for the same printer. Remove old entries and keep only the working wireless instance. This prevents printing to an offline or incorrect queue.

Reset the Printer Network Settings

If nothing works, reset the printer’s network settings and start fresh. This clears old credentials and returns the printer to setup mode. Then repeat one of the setup methods above.

Restart the Router

A simple router restart can resolve DHCP, DNS, and temporary wireless issues. Unplug the router for about 30 seconds, plug it back in, wait for internet service to return, and then retry printer setup.

Connection Methods Comparison

Different setup methods suit different situations. The table below compares the most common options.

Method Best For Requirements Difficulty Notes
WPS Fast setup Router with WPS button Easy May be disabled on some routers
HP Smart App Most users Smartphone or computer, Wi-Fi credentials Easy Best guided experience
USB Cable First Weak Wi-Fi or failed discovery USB cable and computer Moderate Provides a stable setup bridge
HP Software Installer Office or advanced setups Computer and internet access Moderate Installs drivers and utilities
Reset and Reconnect New router or changed password Access to network settings Moderate Clears old credentials

Network and Security Best Practices

Connecting a printer to Wi-Fi is not only about convenience; it also involves network security. Printers can store network information and may be accessible on your local network, so a few precautions are worthwhile.

  • Use WPA2 or WPA2/WPA3 mixed mode for broad compatibility.
  • Choose a strong Wi-Fi password with uppercase and lowercase letters, numbers, and symbols.
  • Keep router firmware updated.
  • Place IoT or guest devices on a separate guest network if your router supports it, while keeping the printer on the main network for easier discovery.
  • Disable WPS after setup if you do not need it, since some security experts consider WPS less secure.
  • Do not share your printer over the public internet unless you understand the security implications.
  • Review connected devices in your router admin panel periodically.

For most home users, the default router security settings are sufficient as long as the Wi-Fi password is strong and the firmware is current. If you operate a small business, consider segmenting printers and computers from guest networks.

Ongoing Maintenance and Firmware Updates

Once the printer is connected, a little maintenance keeps it reliable. Firmware updates can improve wireless stability, fix bugs, and add compatibility with new devices.

  • Open HP Smart periodically and check for printer updates.
  • Keep your phone, tablet, and computer operating systems updated.
  • Restart the printer occasionally to clear temporary states.
  • Keep ink levels adequate; low ink does not usually affect Wi-Fi, but it prevents wasted troubleshooting.
  • Clean the printer exterior and keep vents unobstructed.
  • Use the printer at least occasionally to prevent ink from drying and to confirm the connection remains active.

If the printer goes offline after a long period of inactivity, wake it, check the wireless light, and print a test page. Many issues are temporary and resolve after a restart.
