To connect your HP DeskJet 3755 printer to WiFi, the recommended method is to use the HP Smart app on your smartphone or computer. First, install the HP Smart app from 123.hp.com or your device’s app store. Then, turn on your printer and reset its wireless network by pressing and holding the Wireless and Cancel buttons simultaneously until the wireless light blinks. Open the HP Smart app, add your printer by selecting it from the detected devices, and follow the prompts to select your WiFi network and enter the password. Once connected, the wireless light on the printer will turn solid blue, indicating a successful WiFi connection[1][2][3][4].
Alternatively, if you cannot use the HP Smart app, you can use the printer’s embedded web server by connecting via Wireless Direct, then entering the printer’s IP (usually 192.168.223.1) in a web browser. From there, use the Wireless Setup Wizard under the Network tab to connect to your WiFi[5].
Key points:
– Use the HP Smart app for easiest setup.
– Ensure the printer is in wireless setup mode (wireless light blinking) by pressing Wireless + Cancel buttons for 3 seconds.
– Select your WiFi network and enter the password through the app.
– The printer supports 2.4 GHz WiFi networks only.
– The wireless light turns solid blue when connected.
– You can add the printer on multiple devices with the HP Smart app to share it across your network.
If needed, a USB cable can be used temporarily during software installation, but wireless setup usually does not require it once the printer is in setup mode[1][2].
