  I am using ActiveReports-v10.3.9175.0 Viewer. I open an .RDF file then i click on the Printer Icon and the Printer Dialog takes up to 20 seconds to display.

  I have not tried newer versions of AR.

  Thanks in advance for your prompt response.

  Hello,

  I am unable to replicate the issue at my end. Please refer the attached video. Could you please confirm that is there anything extra are you doing to print the report.

  Thanks,

  Thanks for the video. I have 1 customer with 160 network printers installed. When they click the printer dialog 15-20 seconds. I have another customer with 12 network printers, it takes 40 seconds to get the dialog. We previously came from AR4 .net framework 2 and i can run this viewer, click the dialog and the list pops instantly.

  If you only have a few printers installed its about a 2 second delay however it you test it with older versions of the viewer you will see the older version is much faster

  Hello,

  Thanks for the information.

  Could you please see if the same problem is reproducible with any other application (except AR) as well.

  Sorry for troubling you again.

  Thanks,

  I tried other types of documents such as .pdf, .docx as well as printing for Internet Explorer.
  
  All applications it tested when clicking the printer dialog worked fine. No performance issues.

  I was using Adobe Reader, MS Word, IE and all worked fine.

  There must be something different in that printer dialog that is perhaps checking all the properties on each printer or something like that.

  Hello,

  Yes, you are right. The latency in print dialog is usually caused when the printer is a network printer or there are multiple printers installed on the machine. For printing, ActiveReports fetches the settings for all the installed printers, hence the delay. If it’s a SectionReport, you can set the PrinterName to “” (empty string) in the Report’s constructor (if it’s a code-based report) or using the report’s object if it’s an rpx.

  Another solution is to use the StandardDialog for printing which can be set using either of the code snippets given below:

  1. Document.Print(GrapeCity.Viewer.Common.PrintingSettings.UseStandardDialog);

  2. Document.Print(GrapeCity.Viewer.Common.PrintingSettings.UsePrintingThread| GrapeCity.Viewer.Common.PrintingSettings.UseStandardDialog);

  Hope it helps.

  Thanks,
  
  Mohit

  Hello,

  Could you please check after using the following code

  
  Dim rpt As New SectionReport ()
              rpt.Document.Load(rdffile)
              rpt.Document.Printer.PrinterName = ""
              rpt.Run()
              viewer1.Document = rpt.Document
  
  

  Sorry for troubling you again.

  Thanks,

  Hello Mike,

  I can see in your video, you are still using default print option. Please refer the attached sample which shows the printing using Standard print dialog.

  Hope it helps.

  Thanks,

  Please help with code changes - i am not seeing a difference in performance

              Report_rpt_m.Document.Load(RDFName_str_p)
              'assign the output document from the report engine to the viewer control
              Viewer_frm_p.arvMain.Document = Report_rpt_m.Document
              'is this the line i should insert to prevent the long printer dialog delay ?
              Viewer_frm_p.arvMain.Document.Printer.PrinterName = ""
  
              'show the form
              Viewer_frm_p.WindowState = FormWindowState.Normal
              Viewer_frm_p.Show()
