Try those drivers for Windows 2000 and if there is no drivers for Win2000 either, most likely you will never make that all-in-one work with XP. Sometimes they just stop supporting some hardware especially if it's discontinued.
Last week I tried to find some drivers for Windows XP for some ancient OPTI sound card for one of my customers, and there is nothing to be found. Latest drivers are for Win98, and they stopped producing that card before Wind XP even got out...
Simple solution is to buy another piece of hardware. Especially those all-in-one printers are unbelievable cheap these days... here in Canada you can get them for as less as 90 dollars, and those are good brands HP, Canon, Lexmark and others...
See here, even at official SAMSUNG site there is nothing listed under the name SF-4200... it starts with SF-5100....
