Print preview ok values not printing on print

Hi,

I have developed a sap-script to print production order picklist. I am getting all values in print preview.When production order is released and saved, it is firing a print on the printer in which some values are not printing. These values are picked up by subroutine pool and printed in layout. some picked values are printed on hard copy but some are not. In debug all values are there. I tried all poosibilities but not successded.

Help from anybody will be appreciated as it is most urgent.

Regards,

Amit
