Windows 7: Printer Wont Print

I have an HP Deskjet F4400 printer that seems to be working properly, but the problem is that when I click print on the computer it won't print. I think the problem has something to do with my laptop because when I scanned a document from the printer, it came up on the screen no problem. When I click print, nothing happens and nothing is added to the list of documents pending to print in the devices and printers.

Help Please

I'm trying to remember exactly what I used to do when this problem occurred. I think I turned the printer on and off, then everything I had tried to print printed. Keep in mind it must be turned off via the power button. Unplugging it and plugging it back in doesn't always have the same effect. Also, if this works for you as it did for me, it will start printing immediately.
