Hi Julio,
Unfortunately, for now it's not possible to print and export a Web chart on the client side by means of XtraCharts. As a workaround, you may use XtraReports - just create a report with a single chart, then put a ReportViewer on the page and print or export it using the ReportToolbar control.
If this workaround isn't suitable for you, please track the following suggestion, and you'll be notified when it's implemented:
