Use 2 HP scanners at the same time

I have the HP all-in-one printer/scanner that came with my macbook, as well as the one that came with my dad's. I have a whole collection of photographs to scan in and I thought I could do double time by using both scanners at the same time on my macbook. Is there a way to use both at the same time even though they require the same program for scanning?

Thank you!
