I need to create a shared file for my mac, HP Photosmart 7520 and Neat Desk for Mac

I recently got a Neat Desk for Mac, at an estate sale (No Warranty)

I also use a HP PhotoSmart 7520 wireless, multifunctional printer (Out of Warranty)

and a MacBook Pro (Out of Warranty)

The instructions for the Neat Desk describe files I should have under the HP utilities folder. Such as the "Scanner Destination" folder I do not have these folders they describe.

I called HP and they felt I would be better off contacting Apple to discuss "Shared Folders" I'm out of warranty with Apple too, so I could use some help,
