Printer Help!!!

[JDMFantasy2k]

Ok i have this printer and i don't have the software for it and instead of going to the hewelett packard website first, dumbass me hooks it up via usb and just assumes that i'm going to have the driver for it which i don't. So i go to the hp website and find my appropriate driver, and follow the instructions (wait for the dialogue then hook up printer) however when i hook up the printer it doesn't detect it, although the screen says that once i hook up the printer and it's on (which it is) that the installation will proceed. SO i'm wondering if there's a way to make the computer forget that i ever hooked up the printer because i'm pretty sure it saved it as an unknown usb device. please help if you need more info just ask but i think that's about it.
