We have code that essentially boils down to this:
CrystalDecisions.CrystalReports.Engine.ReportDocument reportDocument;
//
// Our code
//
reportDocument.PrintToPrinter(printerSettings, pageSettings, false);
At runtime, we have confirmed the following (when user wishes to print simplex) are all set to PrinterDuplex.Simplex when passed to PrintToPrinter():
pageSettings.PrinterSettings.Duplex
printerSettings.DefaultPageSettings.PrinterSettings.Duplex
printerSettings.Duplex
Yet in some circumstances, this is being ignored and the report is printed duplex. The behaviour is as follows:
- Set printing preferences in control panel to 1-sided
- User generates a report and specifies explicitly to print 1-sided
- Report is printed 1-sided
- Set printing preferences in control panel to 2-sided
- User generates a report and specifies explicitly to print 1-sided
- Report is printed 1-sided
- Set printing preferences in control panel to "Use printer settings"
- User generates a report and specifies explicitly to print 1-sided
- Report is printed 2-sided
The printer this has been confirmed with is using the Lexmark Universal PS3 driver.
The CrystalDecisions.CrystalReports.Engine assembly being referenced is version 13.0.2.469.
Any suggestions on what may be causing this?
