Reconnect HP Deskjet 2540 to Wireless Network

[CJC182]

I got a new router and now my HP 2540 Deskjet printer won't connect to my network.

I am trying to download drivers, etc but nothing will help since the printer can't be recognized.

Can anyone help?

I have Netgear Orbi 50 router and an iMac.

@CJC182, Welcome to HP Support Community!

Connect a printer that does not have a touchscreen control panel

Use Wi-Fi Protected Setup (WPS), HP Smart, or temporarily connect a USB cable to establish a wireless connection between your printer and network.

Step 1: Connect the printer with WPS

Use WPS to connect the printer to your wireless network.

1. Locate the WPS button on your router, but do not press it yet.

   If your router does not support WPS, skip to the next step to connect the printer with the HP Smart app.

2. Turn on the printer. If the printer is in sleep mode, press the Cancel button on the control panel.

3. On the printer control panel, press and hold the Wireless button  for at least 3 seconds or until the wireless light starts to flash.

4. On the router, press and hold the WPS button for 3 to 5 seconds or until it shows that the WPS connection process has started.

   Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.

Step 2: Connect the printer with the HP Smart app

Use the HP Smart app to connect the printer to your wireless network from computer with Windows 10 or an Android or Apple mobile device.

Use the HP Smart app to connect the printer to your wireless network.

NOTE: 

The HP Smart app is only available for select printer models with Mac computers.

1. Make sure your computer is connected to your wireless network.

2. Download and install the HP Smart app from 123.hp.com.

3. Turn on the printer. If the printer is in sleep mode, press the Cancel button on the control panel.

4. Press and hold the Wireless and Cancel buttons until the Wireless light and Power light starts to flash. You must complete the network setup within 2 hours.

5. On your computer, open the HP Smart app.

   • If you are using the HP Smart app for the first time, the app automatically searches for new printers.

   • If you have used the HP Smart app before, click the Printers tab.

6. Click Set Up a New Printer, and then click Continue.

   HP Smart searches for printers on your wireless network.

7. Select your printer, and then click Continue.

8. When prompted, type the WEP or WPA key (network password).

   If you do not know your network password, go to Find Your Wireless WEP, WPA, WPA2 Password.

9. After the printer connects to your wireless network, click Continue, and then click Exit Setup.

   Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.

Refer to the document HP Printers - No Connection after Router or Wi-Fi Settings Change for help.
