Can't scan from HP Photosmart C7280 to my Mac Computer

I have read the instructions telling me to press Scan Menu and then press Scan to my Computer. BUT THERE ISN'T A STATEMENT SAYING:  SCAN TO MY COMPUTER. I have tried other options on the list but haven't been successful. (Scan and Reprint; Scan to Memory Device; Tiff To Preview; Jpeg to HP Photosmart Share; Jpeg to HP Photosmart Studio; Jpeg to iPhoto; Email to Apple Mail;  Email to Entourage;  OCR to TextEdit; OCR to MSWord;  PDF To Preview) these are my options, please help me to find out which one I should use. Thanks in advance, Colleen My HP 6180 all in one gives me the option to scan and reprint and scan to memory device. I want to scan to my Mac.
What do I do? I had more options before I thought.
