Timeout = ManagementOptions.InfiniteTimeout,Īuthentication = AuthenticationLevel.PacketPrivacy, Private static ConnectionOptions GetConnectionOptions()ĬonnectionOptions connOptions = new ConnectionOptions() ReturnImmediately = true, //Pseudo-async result For more information about running command line tools from within a script take a gander at. If you wanted to, you could wrap this command up in a VBScript and execute the test page from there. Rewindable = false, //Forward only query => no caching However, you can print a test page from the command prompt using this command: rundll32 printui.dll,PrintUIEntry /k /n \\atl-ps-01\color-printer. Helper methods: private static EnumerationOptions GetEnumerationOptions(bool DeepScan)ĮnumerationOptions mOptions = new EnumerationOptions() Using (ManagementBaseObject moResult = moPrinter.InvokeMethod("PrintTestPage", moParams, moMethodOpt)) Using (ManagementBaseObject moParams = moPrinter.GetMethodParameters("PrintTestPage"))

This gives means to correct/adapt the code to specific contexts, when necessary.Īlso, the helper methods here can be reused to initialize any other WMI query.įor example, a wrong Impersonation option, will result in an exception ( 0x80070005: (E_ACCESSDENIED)) when connecting to the WMI Scope or when the WMI query is executed.Ī description of the PrintTestPage method parameters: Now, this method might look verbose, but I think it's important, when calling WMI methods, that the Management Options and Scopes are defined correctly.
