Prevent bookmarklet to be executed on page

Question

I sometimes use Print What You Like service via bookmarklet http://www.printwhatyoulike.com/bookmarklet Today I noticed that it does not work on this page http://www.if-not-true-then-false.com/2012/howto-change-runlevel-on-grub2/ Is there any possibility that author of the page can prevent using bookmarklets on his page?

Answer 1

Tested in Firefox, runs fine.

Yes, there are ways to prevent most bookmarklets from running. The methods are designed to reduce cross site script security exploits, but bookmaklets can suffer as collateral damage. However that site does not appear to be using any such methods.
