You could do something like this example:

In cell A1 have: "Please enter number of pages you want to print-> "
Align that cell right.
In cell B1 have the number of pages to print.
Name the cell B1, NumOfPages
When you name the cell that contains the number of pages, this code will work with the 2 cells just about anywhere you want the page number to show.
Have a button or keystroke run the PrintPages macro below.

'Subs I made because I forget how to do a cell offset all the time
Sub MoveLeft(NumOfCells)
    ActiveCell.Offset(rowOffset:=0, columnOffset:=(-1 * NumOfCells)).Select
End Sub
Sub MoveRight(NumOfCells)
    ActiveCell.Offset(rowOffset:=0, columnOffset:=NumOfCells).Select
End Sub

Sub PrintPages()
    Range("NumOfPages").Select
    NumOfPages = ActiveCell.Value
    MoveLeft (1)
    ActiveCell.Value = "Page: "  'Change prompt temporarily
    MoveRight (1) 'Back to the NumOfPages cell
    For Ctr = 1 To NumOfPages
        ActiveCell.Value = Ctr
        ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True
    Next Ctr
    MoveLeft (1)
    'Put the prompt back on the screen.
    'It would be cleaner with a message box now that I think about it.
    'But, this works too.
    ActiveCell.Value = "Please enter number of pages you want to print-> "
End Sub

Hope it helps
