Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
What is the make and model number of the printer you are using?
I haven't heard back from you yet - please reply and let me know if you still need assistance with this.
Ok, can you try trashing the existing print drivers for your Photosmart 7510 and then install the latest print drivers for Mac Sierra from the HP website?
Let me know if that works...

Can you print from any other applications? If not, then the printing problem should not be caused by Office.
Let me know how reinstalling the print driver goes.
