Print multiple reports at once

I want multiple reports send at once to the printer.

the following code gives me three times the print dialog:
plugins.jasperPluginRMI.jasperReport(controller.getServerName(),_report1,true,‘print’,params, myLocaleString);
plugins.jasperPluginRMI.jasperReport(controller.getServerName(),_report2,true,‘print’,params, myLocaleString);
plugins.jasperPluginRMI.jasperReport(controller.getServerName(),_report3,true,‘print’,params, myLocaleString);

I want to send _report1, _report2 and _report3 all at once to the printer. Is this possible?

In the third parameter: boolean showPrintDialog put true only in the first report.
