Modern technology allows you to do away with cumbersome wires and print documents directly from your smartphone, making work in the home office or while studying much easier. HP DeskJet 3790 It's one of the most compact inkjet MFPs, and its wireless connectivity opens up a wide range of possibilities for mobile device users. Connecting this printer to your phone via Wi-Fi doesn't require extensive technical knowledge, but it does have its own nuances that must be considered for stable operation of the entire system.
During the setup process, it is important to understand the difference between connecting through a home router and using technology Wi-Fi Direct, as the choice of method depends on your current needs and internet access. If you want to print from anywhere in the world with internet access, you'll need the first option, while the second is ideal for quick photo printing without internet access. In this article, we'll examine both methods in detail, focusing on installing the necessary software. HP Smart and eliminating typical errors.
It's worth noting that connection stability directly depends on whether you entered your passwords correctly and the version of your smartphone's operating system. For all scanning and printing features to work properly, iOS version 15.0 or later is required, and Android version 8.0 or later is required.Before starting the procedure, make sure your device is fully charged and your router is operating normally to avoid interruptions during the most crucial setup process.
Equipment preparation and compatibility testing
The first step before starting any network configuration is to physically prepare the device and ensure it is ready for operation.

You must also turn on the device and wait until the power indicator stops blinking, indicating that the printer's operating system has fully loaded.
The second important aspect is checking your mobile device and router. If you plan to use a standard local network connection, your phone and printer must be within range of a strong signal. Dual-band routers can create complications if they broadcast both 2.4GHz and 5GHz networks under the same name, so for initial setup it is recommended to temporarily separate them or use the 2.4GHz network.
⚠️ Note: If your router uses MAC address filtering, you must whitelist the printer's address in advance, otherwise the connection will be blocked even with the correct password.
Finally, make sure your smartphone has the necessary permissions to install apps from the store. On Android, this may require you to confirm installation from unknown sources if you're downloading an APK file from outside of Google Play, although for HP Smart This is rarely necessary.

If the printer HP DeskJet 3790 If you were previously connected to another network, the program may prompt you to reset your network settings, which is the correct action in this case.
During installation, the app will request permissions to access geolocation and local network. This is critical, especially for Android users starting with version 10, where Wi-Fi scanning won't work without geolocation permission. Denying these permissions will result in the printer search returning no results, leading you to believe the device is faulty.
