Thank you very much. Your print_version is exactly what I needed to move on.
Here is my actual working code:

Spoiler:

class AdvancedUserRecipe1285425351(BasicNewsRecipe):
    __license__  = 'GPL v3'
    __author__  = 'Radim Pešek'
    title = u'iDnes.cz'
    publisher = u'MAFRA a.s.'
    description = 'Zprávy iDNES.cz - přehled nejnovějších událostí z domova i ze světa'
    oldest_article = 7
    max_articles_per_feed = 100
    encoding = 'cp1250'
    language = 'cs'
    cover_url = 'http://g.idnes.cz/u/loga-n4/idnes.gif'
    remove_javascript = True
    remove_tags = [dict(name='div', attrs={'class':['related', 'authors','back ico','fl','fc0','ico art-add']})]

    def print_version(self, url):
        split_url = url.split("?")
        print_url = 'http://zpravy.idnes.cz/tiskni.asp?' +  split_url[1]
        return print_url

    feeds = [(u'Z domova i ze sveta', u' http://servis.idnes.cz/rss.asp?c=zpravodaj')]

Please, can you help me how to fix bad diacritics in Section List and Article List on my Kindle (articles have correct diacritics). The website uses cp1250 encoding.
