If you have a CD drive in your laptop and the printer comes with a CD with the installation program, just put it in and the install program should start immediately. Then just follow the screen prompts.
If your laptop doesn’t have a CD drive, Go to the printer manufacturer’s website and download their driver for your OS and if they also include the installation program, download that too. Hookup the USB cable (which likely came with the printer) and when a popup message says to install the driver, point it to the folder you downloaded the driver into and follow the screen prompts.
