Congratulations on publishing such huge books, I can't imagine how much work it is.
I self-published a programming book on C#, it's a bit less than 300 pages and that took a long time to finish.
1 EUR per copy sounds like a really bad deal though? I imagine the book is selling for at least 30 EUR so if you have a normal author royalty of ~16% that would at least give you 5 EUR.
If you self-publish through Amazon(CreateSpace) you get about 50% royalties and you don't have to pay any upfront fees to get it printed since the cost for printing is take out of the other 50%.
