if there's an exe there should be an install folder in windows\program files\samsung (that's what mine's called) - the inf should somewhere in the subfolders usually under 'printer'. otherwise you can find the drivers in the corresponding folders below:
32bit --> c

windows\system32\spool\drivers\w32x86\3
64bit --> c

windows\system32\spool\drivers\x64\3
good luck.
