I understand that Microsoft Office is eager to secure me as much as it is possible. And therefore there was introduced a "read-only" mode. How Microsoft / Windows / Office "knows" which of my private files come from the Internet and which don't? It gives me the creeps... Moreover, it seems to be a cool, security-oriented feature. But why it works for printing documents too?
What harm can I do myself or to my computer, even though the document contains a malicious code or any other kind of unwanted content if I print it out on a piece of paper? Will that execute some harmful macro? Is there any reason or sense behind this, except for pissing me off each time I have to click on Enable Printing button on such docs?
