It typically consists of 8 characters.

Parameter Description Where to find
Network name (SSID) DIRECT-xx-HP DeskJet 3700 series List of Wi-Fi networks on your phone
Password 8-digit code Configuration report or sticker
Range of action Up to 10 meters Depends on the obstacles
Maximum devices 5 connections Technical specifications

When using Wi-Fi Direct, keep in mind that the connected device may lose internet access if it doesn't support two Wi-Fi networks simultaneously. Modern smartphones can usually switch between networks without interrupting the internet connection, but on older laptops, the internet may be lost while printing.

Solving common connection problems

Even if all instructions are followed, situations may arise when HP DeskJet 3788 The printer refuses to connect to the network. A common cause is incorrect network security.
