Error - "No printers are installed."

marsh1n · Post by **marsh1n** » Thu Jan 06, 2011 10:49 am

I am evaluating the .net components. I am running the report in my asp.net application. When i try to export a report, I get the following error:

"No printers are installed."

Here is the code I am using:

Dim oStream As New MemoryStream
Dim TheReport As New Reports.Report

TheReport.Render()
TheReport.ExportDocument(StiExportFormat.Pdf, oStream)

The error occurs on the last line of code.

Any ideas?

Hello,

Which version of Stimulsoft Reports do you use?

Thank you.

I have Stimulsoft Reports.Net 2010.3 Trial.

Just a little more information, this only happens when you use IIS as the web server. It does not happen with the ASP.NET development server., which is what the samples use.

I did a little more research and found out it has to do with the IIS account not having access to printers. I believe there are workarounds which involve making registry changes.

Does the export code actually need a printer installed?

Thanks.

Hello,

Can you show full error stack for this problem? Did you use RichText component in your report?

Thank you.

Hello,

Richtext component have installed WYSIWYG property to true? Richtext use printer canvas for special metafile rendering. This mode work only when WYSIWYG property of Richtext equal to true. Printer canvas used for avoiding strange bug of MS realization of drawing Richtext to metafile (Richtext with high resolution can be draw only on printer canvas).

Thank you.
