To connect the **HP DeskJet 2855e** printer to Wi-Fi, use the printer’s touchscreen to access the **Wireless Setup Wizard**: select your Wi-Fi network (SSID) from the list or enter it manually, then input the network password to establish the connection. The printer will confirm once successfully connected[1].
Detailed steps:
1. Turn on the printer and ensure your wireless network is active.
2. On the printer’s control panel, navigate to **Wireless** or **Network** settings using the color touchscreen.
3. Select **Wireless Setup Wizard** or **Network Setup Wizard**; the printer will scan for available networks.
4. Choose your Wi-Fi network from the displayed list or manually enter your network’s SSID if it’s not listed.
5. Enter your Wi-Fi password accurately when prompted (passwords are case-sensitive).
6. Confirm and wait for the printer to connect; a confirmation message will show once connected.
7. For verification, you can print a wireless network test report from the printer’s menu[1].
Alternatively, you can use the **HP Smart app** on your phone or computer to add the printer and follow the on-screen instructions to connect to Wi-Fi by selecting your network and entering the password, then pressing the printer’s information (i) button when prompted during setup[3][4].
If the Wi-Fi connection fails or the Wi-Fi icon blinks, try restarting the printer or resetting the wireless settings via the control panel and then reconnect[5]. Additionally, the printer supports **Wi-Fi Direct** for direct printing without Wi-Fi network setup, which can be enabled by pressing the Wi-Fi button until the Wi-Fi Direct icon appears solid on the screen[2].
