My son gave me an HP Scanjet 4300C, with no power cord and no USB cord. he did include the software CD, however. 1. I went to the HP web site and can't get a power cord from them. Does anyone have a solution about getting a substitute power cod that will work? 2. I looked at the software on the CD, but I still can't tell if it can be used on a Mac and which OS. Does anyone have one of these scanners and can tell me? If I can't use it, I can pass it on to someone else. Jane
