Crystal report start with blank space in every new pages including first

Dear All,

I have been facing with a serious issue when I print a crystal report in roll paper printer.

My CR page size is 8cm x 12 cm. When I print (direct to printer) Crystal report start with 7cm blank space in every new pages including first one.

For getting continues print (in the case of more number of rows in detailed section ), I have ignored 'page header and page footer' in design and set margin top and bottom to 0. 

I have uploaded all screenshots.

Please help to solve issue.

Thanks in advance
