I have a differnt printer at each pos register. One is a epson tmu220 and the other is star sp512 on both of these i have it so it doesnt print each transaction. But if I do tht it doesnt print it says that it cant find the opos driver. If i have it print only after it ask the transaction it works fine. At one point it was working with it like that but now it isnt. Does anyone have any ideas of how I get it back todo that again?
