Does anyone know what the registry key is to uncheck the Collate check box in
the Print Dialog Box.
KB Article listed below explains the problem of "Separate jobs ar sent when
you print multiple copies of excel.
This only works until you close out of excel and open it back up again. I
would like to find a permanent fix to this problem.
