How can I make catch Printing Events?

Question

When we open an internet explorer(IE6 or IE7) and select File->Print
a print dialog is obtained, how can we catch these, and how can we catch the data that is going to printer, If there are 5 printers installed  then how can we know the Printer name which is selected for printing(not the default printer's name),
how can get the BeginPrint, EndPrint, PrintPage Events fired?
