How to speed up printing in crystal report ....

Hi,
        I am using crystal report printing in my dot net application, but it takes a lot of time to print the reoports, I search over the internet to increase the printing speed then I get some tips that to prevent the preview of the report. I did that and I get a 2-3 seconds earlier printing than that of the print by showing the preview but it is not a good solution I think, So I need a better option to make my printing faster if anybody have the solution please help me...
or suggest your ways to increase the speed of my printing....

Thanks in advance...
