When your WiFi password changes, your printer won’t automatically reconnect unless it is updated with the new network credentials. This often results in printing errors, offline status, or failed print jobs. In this guide, we will walk through exactly how to add a new WiFi password to your printer connection, covering popular printer brands, control panel methods, app-based setup, and advanced troubleshooting.

Why Your Printer Needs the Updated WiFi Password?

A wireless printer stores your WiFi network name (SSID) and password inside its saved configuration. Once your router password is updated, the printer will continue trying the old credentials and will fail to authenticate.

Common signs include:

• Printer shows Offline

• Printing stuck in queue

• “Cannot connect to printer” error

• Printer connected to wrong WiFi network

• Printer blinking WiFi light or network icon

To fix it, we simply need to update the WiFi password in the printer’s wireless settings and reconnect.

Before You Start: What We Need Ready

To complete the setup smoothly, we recommend preparing these essentials:

• Your new WiFi password

• Your WiFi network name (SSID)

• The printer powered ON

• Printer within range of your router

• A phone or computer connected to the same WiFi network

• Printer’s model name (example: HP DeskJet 2700, Canon PIXMA, Epson EcoTank, Brother HL-L2350DW)

Method 1: Add New WiFi Password Using the Printer Control Panel (Best for Most Models)

Many printers allow updating WiFi directly from the built-in screen or buttons.

Step-by-Step Wireless Password Update

1. On the printer, press Home or Menu

2. Open Settings

3. Select Network Settings or Wireless Settings

4. Tap Wireless Setup Wizard

5. Choose your WiFi network (SSID) from the list

6. Enter the new WiFi password

7. Select OK / Apply / Connect

8. Wait for confirmation such as:

• Connected

• WiFi icon solid

• Network status: Online

Tip: If your printer uses arrow keys instead of a touchscreen, enter the password carefully with the keypad selector.

Method 2: Add New WiFi Password Using WPS (Fastest Router-Based Connection)

If your router supports WPS (Wi-Fi Protected Setup), we can connect without typing the password.

WPS Button Connection Steps

1. Turn on the printer and ensure it’s ready

2. Press the printer’s WiFi button (or go to Wireless Settings)

3. Select WPS Push Button

4. Within 2 minutes, press the WPS button on your router

5. Wait for the printer to connect

If successful, the printer will show:

• Connected

• A steady wireless light

• A network connection report confirming WiFi access

Important: Some modern routers disable WPS for security. If WPS fails, use the manual method.

Method 3: Update Printer WiFi Password Using a Mobile App (HP, Canon, Epson, Brother)

Most major printer brands provide official apps that simplify wireless setup and password updates.

Recommended Printer Apps

• HP Smart (HP printers)

• Canon PRINT Inkjet/SELPHY

• Epson Smart Panel

• Brother iPrint&Scan

App Setup Steps

1. Install the official printer app on your phone

2. Open the app and sign in (if required)

3. Tap Add Printer or Set Up a New Printer

4. Put the printer into WiFi setup mode

5. Select your WiFi network

6. Enter the new WiFi password

7. Confirm connection and complete setup

Best practice: Keep Bluetooth enabled during setup if the app requests it. Many apps use Bluetooth to transfer WiFi credentials quickly.

Method 4: Add New WiFi Password to Printer Without a Screen (DeskJet, Laser Printers, Compact Models)

Some printers don’t have a display screen, which makes WiFi updates slightly different.

Option A: Use the Printer’s WiFi Reset Mode

1. Press and hold the WiFi button for 5–10 seconds

2. Wait for the wireless light to blink (setup mode enabled)

3. Use the brand app (HP Smart / Epson Smart Panel / Canon PRINT) to reconnect

Option B: Use USB Setup (Most Reliable)

If wireless setup keeps failing, we can connect using a USB cable:

1. Plug the printer into the computer via USB

2. Install the official printer driver/software

3. Open printer setup utility

4. Select Wireless Setup

5. Choose your WiFi network and enter the new password

6. Save settings and disconnect USB after successful wireless connection

Troubleshooting: Printer Still Not Connecting After Updating WiFi Password

If your printer refuses to connect even after entering the correct password, we can fix it using these precise steps.

1. Confirm the WiFi Password Is Correct

• WiFi passwords are case-sensitive

• Avoid accidental spaces at the end

• Confirm the router is using the correct security mode (WPA2/WPA3)

2. Restart Everything

Power cycle in the correct order:

1. Turn off the printer

2. Unplug router for 30 seconds

3. Plug router back in and wait for full internet

4. Turn printer back on

5. Try reconnecting again

3. Reset Network Settings on the Printer

Most printers have a Restore Network Defaults option:

• Go to Network Settings

• Select Restore Defaults

• Reconnect using the setup wizard

4. Check If the Printer Is Connecting to 2.4GHz vs 5GHz

Many printers only support 2.4GHz WiFi.

If your router separates bands:

• Connect printer to 2.4GHz SSID

• Avoid using 5GHz-only networks

5. Move the Printer Closer to the Router

Weak signal causes:

• Authentication failures

• Dropped connections

• Offline printer status

6. Update Printer Firmware

Outdated firmware can break wireless compatibility.

• Use the printer app or printer settings to check Firmware Update

• Install updates and reboot

Best Practices to Prevent Future Printer WiFi Issues

To keep wireless printing stable long-term, we recommend:

• Use a strong WiFi password but keep it stored securely

• Avoid changing SSID frequently

• Assign a static IP address to the printer (optional but excellent for offices)

• Keep printer firmware updated

• Use the official driver and utility software for your printer model

Quick Checklist: Confirm Your Printer Is Fully Reconnected

After entering the new password, confirm:

• Printer shows Online

• Wireless icon is solid

• Printer appears in your phone/computer printer list

• A test page prints successfully

• No pending print queue errors
