but I don't! :^( I have had an HP LaserJet 1200 for many years, and Software Update was able to quickly update the HP drivers in my new Snow Leopard system. However, I just did a manual check on Software Update - and it came back with info saying I had Canon printer drivers to update! I ain't got no Canon printer! ;^) In Library -> Printers, there is an "InstalledPrinter.plist" file - I looked at it, and there is some weird stuff in it. Under the "InstalledPrinters" section, the HP LaserJet 1200 is there - but so is a bunch of other stuff: my Canon LiDE 200 scanner, HK Soundsticks, the Matsushita optical drive, WinTV (?), and what looks like the Apple Airport Express, plus 6 other manufacturers that are just numbers (1193, 1293, 1532, 2643, 2652, and 8256). What in the world is all this stuff doing in the printer section? And can I / should I edit this file and get rid of anything that isn't a printer? Thanks . . .
