what is an printer usb cable used for please answer?

hooking up your printer to your computer.....
connecting your printer to your computer. lol
I hold my printer hooked up to the router through my usb port, and that allows my whole framework to print (even laptops print wirelessly through it).



Many printers now own both usb and ethernet ports. In case you want to connect directly to your comp, or surrounded by case you would approaching to connect to a router (or both simultaneously).
It allows a printer to communicate with a computer. The cable go from the USB port on the printer to the USB port on the computer. If there is zilch that enables communication between the two devices, afterwards the printer is worthless.
Connecting to USB port of computer instead of parallel port.
