Need help with my form.?

i have a form where many users are using. There is a button there that when clicked, the form's serial number will be incremented by 1 and will be printed. I want that user can only print this form using the button I have provided and that if a user use Ctrl+P or click the printer icon in the tollbar, excel will not print and will rather ask them to click the button provided. A million thanks to those who can provide me the vba code for this. I will treat it as your greatest christmas gift to me. Thanks.
