I made this file by using HP Scanning Software version 4.5 which has no setting for specifying the type of PDF other than things like resolution, sharpness, etc.
Well, it sounds like you've scanned the source as an image and saved it to a PDF. You'd be better off scanning it to one of the more common image formats (such as TIFF) and using an image editor like Photoshop (expensive) or The Gimp (free) to overlay highlighting on the selection.
Even better, scan the original using the IRIS OCR software that comes with your HP, and save it to a Word document. Then you can do pretty much whatever you want with the resulting text.
