Need some help using my scanner

Hey Everybody!

I just recently bought my MBP and have yet to try and scan anything using my HP All-in-one printer/scanner/copier until a few moments ago. Printing is not a problem. But I am having trouble scanning a document. I have a button on the printer for a "quick scan" but when I press it, it shows that it is not connected to a USB port. But indeed it is, and my MBP shows the computer connected to the device. Any advice on what I may be overlooking will appreciated.

Thanks
