How to Run a Silverlight enabled WCF service as a Specific Domain User
Posted on 2011-09-06
I am using Silverlight 4 and a Silverlight Enabled WCF Service. I have a Print button which makes an Async call to my service...see service code below. The goal here is to get my service to automatically print a report to a specific printer and drawer.
Using a Printer Settings object, it is listing the installed print devices for the service, which are not the printers installed on my machine.
We have found the following... "The user running the web service (usually the system or ASPNET account) must have a printer installed and must have permissions to print to that printer. Typically it's easiest to create a Domain account to run the web service. Then you can log in as that account, create a printer and test printing."
Another person suggested... "You should get the identity of the current user at a point in the service when you are scanning printers. My guess is you are running as an anonymous user or someone other than your personal domain account. If this is the case you need to run the service as a specific domain user with access to these printers."
We are running our service authentication at:
Anonymous - Disabled
ASP.NET Impersonation - Disabled
Form Authentication - Disabled
Windows Authentication - Enabled
How can I run the service as a specified domain user?
//SERVICE CODE BELOW
public void PrintFormLetter(FormLetterReports reportInformation)
if (PolicyAdminManager.CanSendFormLetters() == true)
FormLetterBasic flb = new FormLetterBasic(reportInformation); // creates the report
System.Drawing.Printing.PrinterSettings printSettings = new System.Drawing.Printing.PrinterSettings();
printSettings.PrinterName = "Snagit 9";
ReportProcessor reportProcessor = new ReportProcessor();
reportProcessor.PrintController = new System.Drawing.Printing.StandardPrintController();
catch (Exception e)
