Photoshop printing background color on all prints that should have no/white background

Hello,

I am having trouble printing photoshop documents.  The background is white or clear yet every time i print, it prints a gray box encompassing the entire image size.  It is not visible on screen so I am assuming it is a printer/printing setting.  I am also sure it is within photoshop because when I save it as a pdf and open in Adobe to print, it does not print the colored background.  I've tried so many things to remedy this...all to no avail.  Please help?  Thanks!
