Visual FoxPro 8 DOS Printing Problem

Accessing printer codes or DOS printing command in visual foxpro ver. 8.0 using OS windows XP, and it won’t print right away. It needs three (3) transactions of printing jobs in order the system will print. Upon exiting or clossing the system, all buffered print jobs from MS Visual Foxpro will come-out and print. I don’t know why? Can you help about this problem.
