I've got a 3month old HP PC, just rebuilt from Recovery disks with very basic config, little extra software, and no extra hardware running Win 7 Pro (upgraded from the supplied Home Premium).
When I listed the Devices and Printers I was missing a USB-connected OKI ML3390 dot matrix printer. Nowhere to be seen. I happen to right click Properties on the CPU icon at the top and it listed two sections - one for the CPU and one for the dot matrix printer ...
I have no idea why this has happened, and how to separate them - can anyone explain this?
