Pdf Creator taking too much time to print the ducoments in Windows 7

Hi All,

I am facing some strange problem with pdf creator. I have installed pdf creator latest version in both of my laptops one with win XP an dthe other with Win 7. I have downloaded some 300 pics which is (TIFF) files if a medical book from internet and try to convert that to pdf using pdf creator. The crazy thing happens here in Win XP laptop it takes hardly less than a minute whereas the laptop which has win7 it takes nearly 20 to 25 min to complete the task. Can you pls help me out what i am missing in win 7 machine after installing pdf creator.
