How can I sniff the Print Screen key so that when it is pressed, a number of events happen on a web page:

1. There will be a dialog box that will pop up so that the user will only have to input the email address of the recipient.
2. The image on the clipboard is automatically attached to the composed mail.

If it helps, I'm using PHP 5.3.5, Javascript and Swift mailer.

This is completely impossible.

You might be able to get access using a signed Java applet. I do that to read some network properties for a web-based Wake-On-Lan service, but I've never tried to access the system clipboard. I suspect that there's probably a better way to do what you're trying but you don't give any information on the actual application to make a suggestion.

You can not access clipboard and other system-specific facilities with javascript, due to security. Let alone sniff the keyboard.
