Hello everyone

I'm using Telerik ReportViewer for about one or two years now without any problems. But since the last update, I'm not able to print a report using the printer name property. I'm using the following code to print a report:

IReportDocument repDocList = new Fertigungsliste("85856917", "1");

// set printer settings

PrinterSettings printSet = new PrinterSettings();

printSet.Copies = 1;

printSet.PrinterName = @"\\bbfs\ADM51";

// create print controller

PrintController printCtrl = new StandardPrintController();

// create report processor

ReportProcessor repProc = new ReportProcessor();

repProc.PrintController = printCtrl;

InstanceReportSource repSrc = new InstanceReportSource();

repSrc.ReportDocument = repDocList;

repProc.PrintReport(repSrc, printSet);

Unfortunately this code doesn't print the report anymore. If I delete

printSet.PrinterName = @"\\bbfs\ADM51";

it works. Then it uses the default windows printer. But this does not help me. I need to set the printer name like in the example above.

Is there a bug in the latest version of reporting?

Suggestions appreciated

Regards,
Danilo

Hello Danilo,

The following code snippet works as expected on my machine which is connected to the network printer specified by name:

IReportDocument repDocList = new Report1();

// set printer settings

PrinterSettings printSet = new PrinterSettings();

printSet.Copies = 2;

printSet.PrinterName = @"\\the name of our network printer";

// create print controller

PrintController printCtrl = new StandardPrintController();

// create report processor

ReportProcessor repProc = new ReportProcessor();

repProc.PrintController = printCtrl;

InstanceReportSource repSrc = new InstanceReportSource();

repSrc.ReportDocument = repDocList;

repProc.PrintReport(repSrc, printSet);

If the printer is not reachable or valid, there must appear a PrintDialog requesting you to select a valid printer. Thus check if the print operation is failing due to the machine. Please double-check the name of the printer and if the machine is connected to that printer.

The machine's Event Viewer may contain more details about the error on print. Please post the error message in order to provide you more accurate suggestions.

Hi Stef

Thank you for your answer.

As I said, before the last Telerik update it worked for me as well. There is no PrintDialog popping up so the printername is correct I guess. The print job does not appear in the printer queue. We haven't done any changes to our printers or to the network, I checked this with our system administator.

There is also no error/warning/information about this in the event viewer. My computer is connected to the network and also to the printer. When I paste "\\bbfs\ADM51" in the addressbar of the explorer, it opens the printer queue of this printer. I'm also able to print documents from e.g. MS Word/Excel etc. using exactly this printer name.

Do you have any further suggestions?

Regards,
Danilo

Hi Danilo,

I can suggest you the following tests:

Test displaying the report to verify the report can be previewed without errors. For the purpose add a WinForms ReportViewer - How to: Add report viewer to a Windows Forms' Form;
Test printing other content with the same PrinterSettings which will let you know if the issue is related to the printer machine and how it is specified. For example use the following code snippet:

public Form1()

      {

          InitializeComponent();

      }

      private void button1_Click(object sender, EventArgs e)

      {

          PrintDocument pd = new PrintDocument();

          pd.PrintPage += new PrintPageEventHandler(PrintPage);

          PrintDialog pdi = new PrintDialog();

          pdi.Document = pd;

          // create print controller

          PrintController printCtrl = new StandardPrintController();

          // set printer settings

          PrinterSettings printSet = new PrinterSettings();

          printSet.Copies = 2;

          printSet.PrinterName = @"\\safeqorssof01\Telerik Default Printer";



          pd.PrinterSettings = printSet;

          pd.PrintController = printCtrl;

          pd.Print();

      }

      void PrintPage(object o, PrintPageEventArgs e)

      {

          int x = SystemInformation.WorkingArea.X;

          int y = SystemInformation.WorkingArea.Y;

          int width = this.Width;

          int height = this.Height;

          Rectangle bounds = new Rectangle(x, y, width, height);

          Bitmap img = new Bitmap(@"C:\Pictures\ab85_r2d2_usb_hub.jpg");

          this.DrawToBitmap(img, bounds);

          Point p = new Point(100, 100);

          e.Graphics.DrawImage(img, p);

      }

Let us know the result of both tests.

Hello Danilo,

If the first suggested test is successful - the report is displayed, this excludes the report as source of the problem.
If the second test fails - printing a PrintDocument, this implies there is an issue with the given PrinterSettings, which is out of the scope of the reporting engine.

My suggestions is to test connecting other printer to the machine and test printing with it. You will have to check with your system administrator if there are any connectivity issues, the name of the printer machine, the printer machine's drivers and other settings that may prevent the silent printing of documents.
