You must first complete the wireless configuration and network connection before proceeding with the HP DeskJet 2540 connection to the laptop. Continue with the software installation process after you've completed these steps. During the software installation process, you will see a "Connect Window." All you have to do now is follow the on-screen directions. Check that the power is turned on and that the wifi light is blinking. If the light is dull, tap it to brighten it up. You'll be asked to choose between a USB and a WiFi connection on the screen. If you don't want to utilise USB, choose the wireless connection. https://prompthelp.us/blog/hp-deskjet-2540-wireless-setup/
