When one buys the HP printer what they usually look to do after this is to learn how to set up the HP printer. One can always contact HP technicians and contact them to set up the HP Printer, but you can also go to the 123.hp.com/setup website and follow simple steps to set up your HP printer.

 A dialog box will show up which will ask you to type in the key, once you have done this the installation process will begin.

The 123.hp.com/setup is actually a website which is set up by HP technicians to help people set up their HP Printer by downloading the printer drivers and other software through this website. On this website you can find directions on how you can connect your HP Printer wirelessly, with help of USB cable and even things like how one can install a cartridge in the printer.
