To install an HP printer on any device (computer, phone, etc. ), you must first obtain the proper HP printer driver. This can be easily accomplished by going to the official HP website at 123.hp.com/setup. However, before you begin your HP Printer setup, keep the following vital considerations in mind. At the time of setup, make sure the HP printer is turned on and linked to the same Wi-Fi network as the system. You can do this by turning on the printer's Wi-Fi button, which will make it discoverable on the network. Before you start the setup, ensure sure your firewall isn't preventing the HP printer driver.
