To connect your HP DeskJet 2548 printer to Wi-Fi, you can use the **HP Smart app** on your computer or mobile device to set up the wireless connection. The main steps are:

1. Make sure the printer is powered on and paper is loaded.
2. Ensure your computer or phone is connected to the desired Wi-Fi network.
3. Download and launch the **HP Smart app** on your device.
4. Sign in or create an HP account in the app.
5. The app should automatically detect your printer. If not, add it manually by tapping the “+” sign.
6. Go to **Settings > Printer Settings > Network Setup**.
7. Choose your Wi-Fi network from the list and enter the Wi-Fi password.
8. Tap **Connect**, and the printer will connect to your Wi-Fi network.

This method enables wireless printing from your computer or phone once the connection succeeds[1].

Additional setup notes and troubleshooting tips include:

– On the printer, press and hold the **Wireless** button for about 3 seconds until the wireless light starts flashing, which puts the printer in wireless setup mode[2][3].
– The HP DeskJet 2548 works only on 2.4 GHz Wi-Fi bands, so ensure your router’s 2.4 GHz network is active and you’re connecting to that, not 5 GHz[2][3].
– If using a new router or facing connection issues, restarting the printer’s wireless setup and checking the wireless network test report (printed by pressing the Wireless and Information buttons together) can help identify problems[3].
– Alternatively, if your router supports WPS, you can connect the printer by pressing the **WPS button** on your router and then on the printer (Wireless button held for 3 seconds). This pairs them without entering a password manually[4].
– If you have trouble with the printer’s minimal display or can’t find its Wi-Fi password, using the USB cable to connect the printer to a computer and transferring Wi-Fi settings via HP Smart app is a recommended workaround[4].
– Keep your printer’s firmware and HP Smart app updated for best compatibility.

If the printer’s wireless light is blinking with an exclamation mark, it usually indicates a failed connection, often due to wrong password, network incompatibility, or signal issues[2][3].

In summary, the simplest and most reliable way to connect the HP DeskJet 2548 to Wi-Fi is via the HP Smart app, making sure the printer is in wireless setup mode and connected to a 2.4 GHz network. If issues persist, try WPS or use a USB cable for setup[1][2][3][4].
