Printing library(System.Drawing.Printin) problems for WEB API

0

I have a situation to print PDF document as a batch(parallel) from Web API. And I have used System.Drawing.Printing Library to print them.

I have noticed the ‘Caution’ mentioned on the Microsoft site (https://docs.microsoft.com/en-us/dotnet/api/system.drawing.printing?view=net-5.0) as below.

Caution: Classes within the System.Drawing.Printing namespace is not supported for use within a Windows service or ASP.NET application or service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions.

As mentioned in the caution I was facing some unexpected exceptions intermittently during print operation as below.

Exception occured in PrintPdf method: The handle is invalid System.ComponentModel.Win32Exception (0x80004005): The handle is invalid at System.Drawing.Printing.StandardPrintController.OnStartPrint(PrintDocument document, PrintEventArgs e) at System.Drawing.Printing.PrintController.Print(PrintDocument document) at System.Drawing.Printing.PrintDocument.Print()

Code snippet:

public void PrintPdf(Stream stream, string printerconfiguration)
        {
            if (stream == null)
                throw new NullReferenceException(nameof(stream));

            using (var document = _pdfDocumentWrapper.Load(stream))
            {
                using (var printDocument = _pdfDocumentWrapper.CreatePrinterDocument(document))
                {
                    var printerName = printerconfiguration;
                    Print(printDocument, printerName);
                }
            }

private void Print(PrintDocument printDocument, string printerName)
        {
                            
            var printerSettings = new PrinterSettings { PrinterName = GetInstalledPrinter(printerName) ?? printerName };
            var pageSettings = new PageSettings(printerSettings) { Margins = new Margins(0, 0, 0, 0) };
            printDocument.PrinterSettings = printerSettings;
            printDocument.DefaultPageSettings = pageSettings;
            printDocument.PrintController = new StandardPrintController();
            printDocument.BeginPrint += PrintDocument_BeginPrint;
            printDocument.PrintPage += PrintDocument_PrintPage;
            printDocument.EndPrint += PrintDocument_EndPrint;
            
            

            Print(printDocument);
        }

Any suggestions or alternative approach for the same would be greatly appreciated.
