As stated by the others, we need as much info as possible.
I use a HP printer, and there is one possibility I can think of off hand.
My HP printer has a special Photo tray that can accept 4x6 tabbed paper. If that is the case, then that tab is outside the printable area and would be left blank. That tab is about a half inch or 14 mm.
Again I don't know what HP printer you are using, so it's hard to say if this is your issue. Mine is a Photosmart 8250.
