To connect wireless printer HP Deskjet 2540, you have two main paths: set it up for the first time using the HP Smart app, or reconnect it by resetting the wireless settings if the connection is lost. Both methods get your printer onto your Wi‑Fi network so you can print from any computer, iPhone, iPad, or Android device without cables.
Reset the printer's wireless settings
Press Cancel on the control panel first if the printer is in sleep mode before starting setup. If your HP Deskjet 2540 has lost its connection or you are setting it up after a router change, reset the wireless settings first. Press and hold the Wireless and Cancel buttons together for about 5 seconds. This restores the printer’s default wireless settings and enables auto wireless connect. After the reset, you have approximately 120 minutes to complete the setup using HP Smart.
Connect using HP Smart on your computer or mobile device
The HP Smart app is the primary way to connect your printer to Wi‑Fi. Follow these steps on a Windows or Mac computer, iPhone, iPad, or Android device:
- Open HP Smart. If you do not have it, download it from the app store or HP’s setup page.
- Choose Add Printer or the plus sign (+).
- If prompted, select Set Up a New Printer and then Continue.
- Follow the on-screen prompts to select your Wi‑Fi network and enter the network password when asked.
One HP community answer says to start setup from a computer or mobile device with HP Smart installed, then click Set Up a New Printer and Continue. Keep your phone or computer near the router during setup. Turn on Wi‑Fi and enable Bluetooth so HP Smart can detect the printer. On an iPhone or iPad, allow the app to use Location Services so it can find the printer and offer solutions. The HP Deskjet 2540 supports only 2.4 GHz Wi‑Fi networks, so ensure your router is broadcasting that band.
Connect using WPS
If your router supports Wi‑Fi Protected Setup (WPS), you can connect the printer without entering a password. Press the WPS button on your router, then within two minutes press the Wireless button on the printer’s control panel. The printer will join the network automatically. This method is useful when you want a quick wireless printer setup without using the HP Smart app.
Connect using HP Wireless Direct
HP Wireless Direct lets you print directly from a device without a router. Turn on HP Wireless Direct from the printer’s control panel, then connect your computer or mobile device to the printer’s Wi‑Fi network (the network name will appear in your device’s Wi‑Fi list). You can then send print jobs without being on a home or office network. This is ideal for printing from a guest device or when your main network is unavailable.
Print from an iPhone or iPad with AirPrint
Once the printer is on your Wi‑Fi network, you can print from iOS and iPadOS devices using AirPrint. The HP Deskjet 2540 series supports AirPrint on iOS 4.2 or later for iPad all models, iPhone 3GS or later, and iPod touch third generation or later. To print, open a document or photo, tap the share icon, select Print, choose your Deskjet 2540, and tap Print. No additional app is needed for AirPrint, though HP Smart is also available for scanning and advanced settings.
Troubleshooting common wireless connection issues
If your printer is not found during setup, confirm that your device and printer are on the same 2.4 GHz network. The Deskjet 2540 does not support 5 GHz Wi‑Fi. If the connection drops, restart your printer and router, then try adding the printer again in HP Smart. When the printer remains unresponsive, reset the wireless settings by pressing and holding Wireless and Cancel for about 5 seconds, then complete setup within the 120‑minute window. If the printer will not join Wi‑Fi, restore wireless defaults by pressing Wireless and Cancel together for about 5 seconds. For persistent issues, ensure Bluetooth and Location Services are enabled on your mobile device, as HP Smart relies on them to detect the printer.
