I'm running Visual Studio 2013, VB .Net, My program generates four similar reports. All must be single sided. They are all executed in the same way. On my PC (Developer) the reports print fine. Once deployed to another PC, 3 of the four reports are fine, the fourth prints in Duplex mode... I have no understanding of why that is.
On the VB Side, I specifically tell it to print Simplex;
'New
printerSettings.Duplex = Printing.Duplex.Simplex
' Select the printer.
ReportName.PrintOptions.PrinterName = printerSettings.PrinterName
'new
ReportName.PrintOptions.Duplex = printerSettings.Duplex ..
