Bad idea, for resource usage and:

More precisely, the better idea is to use a *print stylesheet*, one that is 
only triggered if the media is “print”.  This is a CSS feature and is not 
related to scripting.  CSS is on-topic in 
<news:comp.infosystems.www.authoring.stylesheets>.

OP: It is outright rude to start a thread in a newsgroup *knowing or 
assuming* that it is going to be off topic.  You are not going to elicite 
answers this way, not many competent ones at any rate, as you are wasting 
people’s free time.  People have subscribed here because they are interested 
in the topic of *this* newsgroup.  If you have difficulty finding the 
appropriate newsgroup, there are newsgroups like 
<news:news.newusers.questions> where you can ask about that.  You can even 
ask in a newsgroup in which the thread is likely off-topic where it would be 
on-topic.  But it does not work as you did.  Please read the FAQ of this 
newsgroup on how to post properly, and do not do again what you did.

Race condition, bad idea.

Worst idea so far, cracking a nut with a hand grenade (*iff* it goes off).
