Its behaviour is strange: Calibre recipe can't succeed in downloading contents, as they seem to be copy protected and there is not a print firendly version. Thus Calibre gives empty ebooks. Never found something similar before.
Can anyone help? Please find attached the temporary recipe I wrote, on which anyone can freely operate.
