Printer installation failure, missing inf files

I'm not sure if this should be in hardware or software, as both are involved. If I'm in the wrong area, please let me know and I'll ask that it be moved.
I've been having major issues trying to get a new printer installed. (Actually, ANY new printer installed!) I've tried 2 different HP printers and 1 Brother, all multifunction all-in-one machines. The software installs smoothly up to the point of plugging in the USB cable. At that point, the installation fails due to 'driver not found' errors. When I dig a little deeper, it is because two system files are missing: usbprint.inf and usbstor.inf. My question is, can these files be located online, downloaded and installed? It suggests to use my OS installation disk(s), but I don't have an actual installation CD. I have the recovery CDs that were burned from my laptop when it was brand new, but I don't know if that's the same thing as the actual installation disk. Any help would be greatly appreciated.
