The term "printing more Euros" is rather inaccurate. When people talk about "printing money" it tends to be an indication that they either (a) don't know what they're talking about or (b) are not interested in an honest discussion.

Printing money is irrelevant. Spending money isn't.

As for the reality: The reality is that there is vast under-utilization of resources in the real economy. That's what a recession is all about, after all. I'm not a growth-fanatic, but real people are hurt by that development via the crazy amounts of unemployment, especially youth unemployment.

Furthermore, this under-utilization is an indication that if someone were to massively increase spending in the real economy, the economy would likely react significantly by adjusting the size of its production, and the reaction in terms of price level would be minimal.

So in that sense, if I indulge your misguided metaphor for the moment, it is actually the anti-printing folk who are wishing reality away: in their fantasy world, the recession will just end without any spending involved. Out here in the real world, this is not how it works.

(But note that the type of spending matters. Just throwing more money into the hands of the financial sectors is not going to help. Direct job creation is necessary, and in the case of Europe, there are some very obvious candidate projects, such as installing large amounts of solar energy capacity around the Mediterranean, along with the transmission capacity. That's just one pet idea though, there are plenty of other useful things to do.)
