I have scanned infrequently but it has always worked before. Now when I push the scan button, it says "scan options are not set. Install or run device software on computer." What happened to the scanning ability - nothing has changed on my computer or printer but now it won't scan. I put the disc in (hp psc 1300 series, psc 2400 photosmart series, hp officejet 5500 series) and it says "you can't open the application hp all-in-one installer because Power PC applications are no longer supported." The reference guide says that it is possible to scan to a computer connected directly to the hp psc. We have a three year old mac and don't really want to buy a new computer or printer. Can anyone help?
