As @WEG mentioned in the answer for JasperReport size limit question it can be done with help of this parameters:

• net.sf.jasperreports.governor.max.pages.enabled - a flag indicating whether the governor that checks if a report exceeds a specified limit of pages is turned on. With this property enabled, the JR engine will stop the report execution if the number of pages becomes greater than a custom given value;
• net.sf.jasperreports.governor.max.pages - if the governor that checks if a report exceeds a specified limit of pages is turned on, this property will indicate the maximum number of pages allowed to be ran, in order to prevent a memory overflow error. If the number of pages in the report becomes greater than this value, the report execution will be stopped;
• REPORT_MAX_COUNT - an integer allowing limit the datasource size.

In the iReport you can find a built in variable PAGE_COUNT. For every element in the detail band you can put the following in the "Print when expression" textbox:

Boolean.valueOf($V{PAGE_COUNT}.intValue() < 100)

This will stop printing after page number 100.
