Okay, so my printer is a HP Deskjet F4280 All-In-One and I just tried printing out something, but it never worked.
I checked that the wire/cable from behind the printer and it was connected to the computer and everything. The power cord is plugged in and is working.
I press print and on the bottom right of my desktop there's an icon of a printer. When I double-click it, it says example: "Document #1... Status: Printing."
But it isn't printing at all.. This also happened with a Lexmark Printer.
