Excel 2007 : Print - Message Box to Select Pages - Help?

I'm using the following code from Mrto allow me to select which pages to print:

Option Explicit

Sub SelectSheets()
Dim i As Integer
Dim TopPos As Integer
Dim SheetCount As Integer
Dim PrintDlg As DialogSheet
Dim CurrentSheet As Worksheet
Dim cb As CheckBox
Application.ScreenUpdating = False

' Check for protected workbook
If ActiveWorkbook.ProtectStructure Then
MsgBox "Workbook is protected.", vbCritical
Exit Sub
End If

' Add a temporary dialog sheet
Set CurrentSheet = ActiveSheet
Set PrintDlg = ActiveWorkbook.DialogSheets.Add

SheetCount = 0

' Add the checkboxes

TopPos = 40
For i = 1 To ActiveWorkbook.Worksheets.Count
Set CurrentSheet = ActiveWorkbook.Worksheets(i)
' Skip empty sheets and hidden sheets
If Application.CountA(CurrentSheet.Cells) <> 0 And _
CurrentSheet.Visible Then
SheetCount = SheetCount + 1
PrintDlg.CheckBoxes.Add 78, TopPos, 150, 16.5
PrintDlg.CheckBoxes(SheetCount).Text = _
CurrentSheet.Name
TopPos = TopPos + 13
End If
Next i

' Move the OK and Cancel buttons
PrintDlg.Buttons.Left = 240

' Set dialog height, width, and caption
With PrintDlg.DialogFrame
.Height = Application.Max _
(68, PrintDlg.DialogFrame.Top + TopPos - 34)
.Width = 230
.Caption = "Select sheets to print"

End With

' Change tab order of OK and Cancel buttons
' so the 1st option button will have the focus
PrintDlg.Buttons("Button 2").BringToFront
PrintDlg.Buttons("Button 3").BringToFront

' Display the dialog box
CurrentSheet.Activate
Application.ScreenUpdating = True
If SheetCount <> 0 Then
If PrintDlg.Show Then
For Each cb In PrintDlg.CheckBoxes
If cb.Value = xlOn Then
Worksheets(cb.Caption).Activate
ActiveSheet.PrintOut
' ActiveSheet.PrintPreview 'for debugging

End If
Next cb
End If
Else
MsgBox "All worksheets are empty."
End If

' Delete temporary dialog sheet (without a warning)
Application.DisplayAlerts = False
PrintDlg.Delete

' Reactivate original sheet
Sheet1.Activate
End Sub


My problem is this...each page prints individually..I want all the selected pages to be a continuous print job....I'm printing to a PDF file and I need page number continuity. Can anyone help?

Thanks
