hi all,

As what I know there is no PRINT button in VS2005 web ReportViewer. But then microsoft do provide a way to render report in EMF for printing. I tried the sample code, but it looks like the printing job is occured at the printer attached to the server. What I want is the printing should be occured at the client printer. Anybody got idea on it ? Is it I missed up something from the sample code ?

Anyone has tried the microsoft EMF-rendering print sample code (for web) and can print at client printer ?

 Thank you.

I wonder how Javascript can do it. I will find it out from johnzen through msn. Thanks johnzen.

Anybody got idea how to do it too, kindly let me know. I really appreciate it.

Thank All.

regards,

Impossible to print at client printer through LocalReport at VS2005 ReportViewer Control ?

The only way is has to export to PDF/Excel first, then print the PDF/Excel file locally ?

No alternative way to print localreport at client printer ?
