hi Sudha,
this depends on what version of crystal reports you have. if you've got crystal reports 2008 or newer, then with your report open, go to the File menu > Page Setup > check the No Printer option.
you can also use the Dissociate Formatting Page.. option to use a custom page size.
if you have an earlier version, then there is no such option. probably the best that you can do in these cases is to ensure that everyone has the latest printer drivers installed.
cheers,
jamie
