printing smartform

hi everyone....

i developed a smartform in which i am fetching data according to date range which i have defined in select-options.

i am getting right data.

the data is the bills issued to various vendors in that date period.....

my problem is that when i execute my program the output is coming for 1st vendor only. for next vendor i have to go back and again click on 'print preview button'. by this i am getting all vendors one by one...... but i want to get all data for all vendors in 1 go......

so plz help me out as soon as possible...
