Sascha, I am afraid Johanna is merely being honest to what is a very 
widespread misconception. Even Walter Bender has challenged me to invent 
a charcoal-based printer.
And that was in response to my assertion, which I am happy to repeat any 
time it is needed, that the lack of printer support by the XO is indeed 
a very valuable feature, not a bug.

I do agree with you about the huge and totally unnecessary waste of 
energy and water that printing would entail.

However, most teachers and so-called education systems are paper-based.  
That is one among many ugly realities we have to deal with, a cognitive 
dissonance that hinders the success to a new POV for education.  
Moreover, even when digital-based, people are not "on the same page", a 
still valid expression...  It was recently mentioned by a Uruguayan 
teacher that the forms that are being sent to be filled out by teachers 
by their national administration are MS Office documents, thus cannot be 
worked (easily) in the XO!

Of course I insist you are right that from a real education point of 
view printing is mostly irrelevant, *compared to* the possibilities of 
collaboration, the web, etc.  But that is, *compared*... :-(.  If 
teachers and students are not using those opportunities either, then it 
is only natural that only what is inked on paper is worth anything.

So, are they using those opportunities?

a simple example: by the end of 2009, Uruguay had over 366.000 laptop 
<http://es.wikipedia.org/wiki/Plan_Ceibal>s or so in the hands of 
teachers and students, and available to be used by their families, etc. 
*However*, by May 15 of 2010, there were only 162 Wikipedia 
<http://es.wikipedia.org/wiki/Wikipedia_en_espa%C3%B1ol#Colaboradores> 
"colaboradores" from Uruguay! One for every hundred teachers, or one per 
every 2.000 students and their families...

As long as we cannot change this kind of approach to the XO or any other 
such tool, teachers will, indeed, "need" to print.
