Bonjour Olivier,
Tu pourras peut-être déjà gagner de précieuses secondes en faisant :
Dim xWorksheet As Worksheet
Dim Calc
Application.ScreenUpdating = False
Calc = Application.Calculation
Application.Calculation = xlCalculationManual
For Each xWorksheet In ActiveWorkbook.Worksheets
xWorksheet.Range("G:G,I:I,J:J,M:M").EntireColumn.Hidden = True
With xWorksheet.PageSetup
.PrintArea = "$B$1:$L$59"
.LeftMargin = Application.InchesToPoints(0)
.RightMargin = Application.InchesToPoints(0)
.TopMargin = Application.InchesToPoints(1)
.BottomMargin = Application.InchesToPoints(1)
.HeaderMargin = Application.InchesToPoints(0.5)
.FooterMargin = Application.InchesToPoints(0.5)
.PrintHeadings = False
.PrintTitleRows = ""
.PrintTitleColumns = ""
.PrintGridlines = False
.PrintComments = xlPrintNoComments
.CenterHorizontally = True
.CenterVertically = False
.Orientation = xlPortrait
.Draft = False
.PaperSize = xlPaperLetter
.FirstPageNumber = xlAutomatic
.Order = xlDownThenOver
.BlackAndWhite = False
.Zoom = 55
End With
Next xWorksheet
Application.ScreenUpdating = True
Application.Calculation = Calc
Cordialement.
