Sorry if I posted this in the incorrect area, but I need some advice. I spent time today with HP's Tech Support about a scanner issue. I'm convinced that it is related to HP's inability to write software for the Mac but the Tech had another reason I wanted to bounce around here. The HP tech said that the reason my scanner took 7 minutes and 32 seconds to scan a 8X11 piece of paper in B&W at 200 resolution to an image file was that my HP all-in-one was plugged into an surge protector. He told me that all HP printers need to be plugged into the wall directly or else it will not get enough power. My BS Detector went off. The HP tech told me that when multiple devices, including desk lamps, cordless phones, computers etc., are plugged into the surge protector, each one reduces the amount of power to each device. I asked, Watts? Voltage? Amps? Increased resistance? He said he had no idea, but it was HP's policy to tell everyone to plug into the wall and not a surge protector. He told me that this was the reason the scanner was so slow. I really don't want a voltage spike to enter my printer, travel through a USB cable or phone line or network cable and into other electrical devices. That's why I have a surge protector. Or so I thought. I also think I remember something about the power brick regulating the small power fluctuations before it hits the device. Can someone clarify this for me?
