#4 Button access

[JC]

Hello i used your backend since a year and it works
fine, but the HP 3300C has 2 buttons, and i thinks it will
be a great thing to ba able to make copie directly by
pressing the copy button.

Is there a possibility to call an external script that can
be used for button1 and button2 (why not to make a pdf
directly, mail, fax the document... with the second
button)

Thanks to your work.
