I want to print HTML from a C# web service. The web browser control is overkill, and does not function well in a service environment, nor does it function well on a system with very tight security constraints. Is there any sort of free `.NET` library that will support the printing of a basic HTML page? Here is the code I have so far, which does not run properly. public void PrintThing(string document) { if (Thread.CurrentThread.GetApartmentState() != ApartmentState.STA) { Thread thread = new Thread((ThreadStart) delegate { PrintDocument(document); }); thread.SetApartmentState(ApartmentState.STA); thread.Start(); } else { PrintDocument(document); } } protected void PrintDocument(string document) { WebBrowser browser = new WebBrowser(); browser.DocumentText = document; while (browser.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); } browser.Print(); } This works fine when called from UI-type threads, but nothing happens when called from a service-type thread. Changing `Print()` to `ShowPrintPreviewDialog()` yields the following IE script error: > **Error:** `dialogArguments.___IE_PrintType` is null or not an object. > > URL: `res://ieframe.dll/preview.dlg` And a small empty print preview dialog appears.
@mruanova None of the answers worked last I tried them. If you have something that works let us know.
