Thank you so much, Dhedges and DIGERATIPRIME. I was finally able to fix this anoying problem with my Samsung ML-1740 printer. I wasted many hours looking for a solution but alas. I aslo tried a couple of different version of WOW32.dll and for me ver. 4.10.0.1998 worked like a charm. I was beginning to think nothing will help. Thank you once again.
