Crystal Report crashed or failed

We have an ASP .Net application developed using Microsoft Visual Studio 2008 and Crystal Report that comes with the Visual Studio 2008. Most of the reports generated are displayed via the Crystal Report Viewer and are also printed to a network printer using PrintToPrinter function. This application is deployed on Windows 2003 server installed with Crystal Report Runtime and .Net Framework. The application is running fine. However after users having printed a few reports, the following errors occurs:

1. Error in File C:\Windows\Temp\....rpt: The request could not be submitted for background processing.
2. The Report Application Server failed.

From Windows 2003 server event viewer, I could find an faulty event:

Windows cannot query DllName registry entry for {CF7639F3-ABA2-41DB-97F2-81E2C5DBFC5D} and it will not be loaded. This is most likely caused by a faulty registration.

Once the above errors occured we would not be able to print or preview the reports anymore. We have to restart the IIS Admin services.

Has anyone of you encountered such problems and has managed to solve this? Will appreciate if anyone of you could give me some advice on how to troubleshoot or solve this problem.
Thank you.

When you close a report do you cleanup the objects?

Yes I did.

Belows are the codes that I used:

PO2PdfReport.Close();
PO2PdfReport.Dispose();
System.GC.Collect();

Did I miss anything?

I don't know ASP well enough to know for sure, but that looks like it.

We suspect that the problem could be due to not having .NET framework installed in those computers. Could it be because of Crystal Report, that .NET framework still need to be installed although this is a web application?

The version that comes with VS 2008 may require the .Net framework.  That version is intended to be used with VS2008 applications and not as a standalone version.

This problem is solved after we had changed to a lower version of printer driver. So, it could be due to incompatibility of the printer driver with Crystal Report for the .NET

Thanks to all who had offered help / comments.
