Gary,
In the report's open event you can use the printer object to set the paper size, margins, etc so that it will be the same on each machine that is using the app. For example,
Private Sub Report_Open(Cancel As Integer)
Me.Printer.PaperSize = acPRPSLegal
Me.Printer.BottomMargin = 0.5 * 1440
Me.Printer.TopMargin = 0.5 * 1440
Me.Printer.LeftMargin = 0.5 * 1440
Me.Printer.RightMargin = 0.5 * 1440
End Sub
Keep in mind that one twip = 1/1440 of an inch so in the above example my margins have been set to half an inch. There are other settings you can change too such as the paper tray, portrait or landscape, manual feed, etc. Have a look at the "Printer" object.
Hope this helps.
Todd
