OnWorkbookBeforePrint property (ExcelListener).

he OnWorkbookBeforePrint provides facilities for trapping an event fired by Excel before directing information to a printer. Consider the following code.


The output of the signature() method indicates that an event handler is expected to accept one argument and return a boolean value. If the last processed event handler returns True then the printing (or opening Print dialog) will be stopped. The following code illustrates the ideas.


Consequently, any output to a printer would be stopped and an attempt would direct output to the ControlShell as show below.
