print a report with text and image on a label

[Roman]

Hi there

I'm trying to print a report with some data from our system on it. The report should be printer as a label. The label has a width of 102mm and a height of 102mm. I'm using this code to print the label:

01.IReportDocument repDocList = new AddrLabel();
02.
03.// set printer settings
04.PrinterSettings printSet = new PrinterSettings();
05.printSet.Copies = 1;
06.printSet.PrinterName = LabelPrinterName;
07.
08.// create print controller
09.PrintController printCtrl = new StandardPrintController();
10.
11.// create report processor
12.ReportProcessor repProc = new ReportProcessor();
13.repProc.PrintController = printCtrl;
14.
15.InstanceReportSource repSrc = new InstanceReportSource();
16.repSrc.ReportDocument = repDocList;
17.
18.// print report
19.repProc.PrintReport(repSrc, printSet);

The report contains text and image. I attached two images. One image is the expected report how it should be printed on the label. We printed that manually on windows photo gallery application to test if our printer is able to print images properly. The second image is how the telerik report is printed. As you can see it doesn't print the image properly (only black & white). It also prints the report on two pages and moves it down and to the right.

I'm wondering if it's possible to print a report on a label and if yes: how?
We're using a TSC TC310 label printer.

Hi Roman,

Please open the report in a Report Designer and check its PageSettings properties: more importantly, the PaperKind and PaperSize including margins, and if the Report Designer points that the content can be gathered in the given physical page size. You can run design-time print preview to check how the physical page will look with the processed data.

If you need further help, please open a new support ticket and send us the problematic report with test data (for example in CSV format) to test it locally.

Hi Silviya,

Thanks for your answer. It helped a lot. I know can print the report on one label. But the coloring does not work yet. I cannot find any settings for the report or for the image to be printed properly as in my attached file "expected_report.png" above. Is there any possibility to print it not only black & white but in grayscale?

Regards,
Roman

Hi Roman,

I tested the gray scale printing issue locally, but couldn't reproduce it. I created a simple report and printed it through the Standalone report designer on a physical printer, and in PDF file with Color output in both cases set to the corresponding equivalent of 'Gray Scale'. The document was printed correctly (entirely in gray scale).
This issue is most probably related to the driver settings of the local printer.

In Telerik Reporting Printing is equivalent to Image Rendering, so I suggest to export the report in .TIFF and test printing the generated image with a third party application in gray scale. If the printed file is correctly converted to gray scale, consider setting the OutputFormat of the Device Info settings for IMAGEPrint rendering extension to TIFF. This can be done by adding the following code to the App.config file of the application:

.....

<configuration>
  <configSections>
  <section
      name="Telerik.Reporting"
      type="Telerik.Reporting.Configuration.ReportingConfigurationSection, Telerik.Reporting"
      allowLocation="true"
      allowDefinition="Everywhere"/>
  </configSections>

.....

  <Telerik.Reporting>
    <extensions>
      <render>
        <extension name="IMAGEPrint" description="Print Rendering Description">
          <parameters>
            <parameter name="OutputFormat" value="TIFF"/>
          </parameters>
        </extension>
      </render>
    </extensions>
  </Telerik.Reporting>

.....

</configuration>

Note that by default the documents are rendered for printing in EMF, which is a vector format. TIFF is a raster format, hence if the printer resolution (DPI) is higher that the resolution used to render the report, the document printed through TIFF may look rasterized.

If the problem persists, I would ask you to open a new support ticket and send us a sample application reproducing the issue to perform local tests.
