Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Printing All or Nothing.
Karen is looking for a way to print an entire workbook, even if a user chooses to print a single worksheet. In other words, she is looking for a way to print either the entire workbook, or nothing at all—there should be no "in between" options.
The only way to handle this is through the use of a macro. VBA allows you to create macros that are initiated when certain events occur. One of the events that can trigger macros is the "print" event. When someone asks to print, or chooses to see a print preview, the BeforePrint event of the Workbook object is triggered. You can create your own macro that executes when the event is triggered.
Private Sub Workbook_BeforePrint(Cancel As Boolean) Dim sht As Variant Dim bPreview As Boolean Dim iResponse As Integer On Error GoTo ErrHandler iResponse = MsgBox(prompt:="Do you want to Print Preview?", _ Buttons:=vbYesNoCancel, Title:="Preview?") Select Case iResponse Case vbYes bPreview = True Case vbNo bPreview = False Case Else GoTo ExitHandler End Select Application.EnableEvents = False For Each sht In Sheets If sht.Visible Then sht.PrintOut Preview:=bPreview End If Next ExitHandler: Application.EnableEvents = True Cancel = True Exit Sub ErrHandler: MsgBox Err.Description Resume ExitHandler End Sub
Whenever Excel gets ready to print, or whenever print preview is invoked, the BeforePrint event is triggered and this macro runs. The macro first asks the user if he or she wants to do a print preview. A Select Case structure is used to set the bPreview variable based on the answer to the question. The setting of bPreview then controls what happens.
If the user clicked Cancel when asked about previewing, then the macro is exited and the printing is canceled. Otherwise, each worksheet in the workbook is examined to either print or preview. If the worksheet is visible, it is printed, and the Preview property is set equal to bPreview (True means that the worksheet is previewed; False means it is actually printed).
Notice that the macro sets the EnableEvents property to False. This is done so that no other events can trigger while printing or previewing. If EnableEvents is left "on," then every time the PrintOut method is used, the entire BeforePrint event is again triggered—the user would end up in an endless loop if event handling were not turned off.
Also, note that one of the last things to occur before exiting the macro is that the Cancel property is set to True. This is done so that the original print or print preview request that generated the BeforePrint event is cancelled. There is, after all, no need to complete that request, and the macro did all the print handling for the user.
There is one caveat, of course, to using this approach to printing: If macros are not enabled, the handler will not run and the user can print as desired. (Holding Shift while opening the workbook disables macros and the user most times is asked if they want to enable macros.) Other issues of ExcelTips have discussed this fact.
