This is my template:

    </pageFooter>
    <summary>
        <band height="42" splitType="Stretch"/>
    </summary>
</jasperReport>

I am just trying to print the JasperReports' report on web page using php.

The problem is while printing on web page, the first page will be blank, in next page it will display the data. I was reducing the band height. but yet there is a extra page appear.

Get rid of your empty bands. You have title, pageHeader and columnHeader bands that have declared heights but are unused. These bands will appear before your detail band. Delete them completely or at least set their heights to zero.

You also have background, columnFooter, pageFooter and summary bands that are empty and could be deleted too.
