USB.CAT file needed Printer

Ive been trying to reinstall my printer which is a PSC HP 2110 All-In-One series and i have a problem with a usb file called usb.cat when searching for devices it gives me a corrupt or missing sorta thing. then asks me to insert windows 98 cd-rom which has been lost = (. a message gives me the option to either insert the cd-rom or browse for the file. i click on the downloaded usb.cat but still insists that this isnt the right thing to do. i downloaded it and its sitting right now in my documents folder under another folder. maybe this isnt a good place for it? i installed it and the file just sits there now. am i doing something wrong??? Plz help me its getting VERY irritating. :mad:
