To connect your **HP DeskJet 4100** printer to Wi-Fi, follow these steps:
1. **Activate Wi-Fi on the printer:**
– Press and hold the **Wireless** button (Wi-Fi icon) on the printer for about 3 seconds until the wireless light starts blinking. This puts the printer in wireless setup mode[1][2].
2. **Use the HP Smart app (recommended):**
– Download and install the **HP Smart app** on your smartphone or computer.
– Open the app and tap the **Plus (+)** icon to add a new printer.
– Select your printer (e.g., “HP DeskJet 4100 Series”) when it appears.
– Follow the on-screen prompts to select your Wi-Fi network and enter the Wi-Fi password (usually found on the back of your router).
– Wait for the printer to connect to your Wi-Fi network[1][2].
3. **Alternatively, use other connection options if preferred:**
– **WPS method:** If your router supports WPS, press the WPS button on your router, then press and hold the printer’s wireless button to connect automatically[2].
– **Wi-Fi Direct:** You can enable Wi-Fi Direct by pressing the **Information**, **Wireless**, and **Resume** buttons together on the printer, then connect your device directly to the printer’s network[5].
If you need to **change the Wi-Fi network** on your already connected HP DeskJet 4100:
– Access the printer’s wireless settings via the control panel and follow steps to select a new network and enter the password[3].
This process generally takes a few minutes and enables wireless printing and scanning from your devices.
