VF31 Sequential Printing

Dear Gurus,

I am using vf31 for sequential printing, problem is when i am choosing 10 billing document and after that execute it, system give me the print job message 10 times every time i have to select print. and then proceed same window again appear every time (10 times).

Is there any setting so that i can avoid this job, just press print only once.

Regards,
