Dimitry,

In case your customer has a printer dog-matrix e.g. which does not support Both sides printed, the solution would be for them to print first the odd pages of the report. take the printed paper and turn it around , than print the even pages.
For that I have in my classes this code:

Parameters tcReport, tcOddEven

Select curReport

Go Top
Set ReportBehavior 90
loOddEvenListener = Newobject("OddEvenListener")
loOddEvenListener.ListenerType	= 1   &&Preview
loOddEvenListener.icWhatToPrint = Upper(tcOddEven)

Report Form (m.tcReport) Object loOddEvenListener

Define Class OddEvenListener As UpdateListener Of "_reportlistener.vcx"

	icWhatToPrint = Upper(m.tcOddEven)

	Function IncludePageInOutput
		Lparameters tnPageNo
		Do Case
			Case tcOddEven = "ALL"
				Return .T.
			Othe
				Return (m.tnPageNo%2=1 And This.icWhatToPrint = "EVEN") Or (m.tnPageNo%2 = 0 And This.icWhatToPrint="ODD")
		Endcase
Enddefine
