Print Control Crystal Report asp.net

[Davix]

Hi,

I need print report from print button viewer direct to printer. I
added to web.config file

<configSections>
<sectionGroup name="businessObjects">
<sectionGroup name="crystalReports">
<section name="printControl"
type="System.Configuration.NameValueSectionHandler, System,
Version=10.2.0.1078, Culture=neutral, PublicKeyToken=b77a5c561934e089,
Custom=null" />
</sectionGroup>
</sectionGroup>
</configSections>

<businessObjects>
<crystalReports>
<printControl>
<add key="url" value="http://localhost/PrintControl.cab" />
</printControl>
</crystalReports>
</businessObjects>
how it is indicated in MSDN, but when I try to print prompt window ask
if I want install Print Control. When I click 'Yes' , empty window
appears but inmediately close and nothing happens.

Somebody knows which is the problem?

Where can I get PrintControl.Cab file? I was searching in
BusinessObjects but I can't find it.

Thanks in advance.
