If you select multiple cell ranges on one sheet and tries to print out selected cells you will get one sheet for each of the selected areas. The following example macro will print all the selected areas on one sheet, except if the areas are too large to fit in one sheet.

Sub PrintSelectedCells()
' prints selected cells, use from a toolbar button or a menu
Dim aCount As Integer, cCount As Integer, rCount As Integer
Dim i As Integer, j As Long, aRange As String
Dim rHeight() As Single, cWidth() As Single
Dim AWB As Workbook, NWB As Workbook
    If UCase(TypeName(ActiveSheet)) <> "WORKSHEET" Then Exit Sub 
    ' useful only in worksheets
    aCount = Selection.Areas.Count
    If aCount = 0 Then Exit Sub ' no cells selected
    cCount = Selection.Areas(1).Cells.Count
    If aCount > 1 Then ' multiple areas selected
        Application.ScreenUpdating = False
        Application.StatusBar = "Printing " & aCount & " selected areas..."
        Set AWB = ActiveWorkbook
        rCount = ActiveSheet.Cells.SpecialCells(xlLastCell).Row
        cCount = ActiveSheet.Cells.SpecialCells(xlLastCell).Column
        ReDim rHeight(rCount)
        ReDim cWidth(cCount)
        For i = 1 To rCount 
            ' find the row height of every row in the selection
            rHeight(i) = Rows(i).RowHeight
        Next i
        For i = 1 To cCount 
            ' find the column width of every column in the selection
            cWidth(i) = Columns(i).ColumnWidth
