+*.jpg +*.jpeg +*.html

Ranges, no, but you can use:
+foo.com/print.phtml?id=*

Wow, quite complex situation. If I understand, you 
want to to capture URLs that aren't linked in the 
index.html, but in deeper pages, without mirroring 
these pages. This isn't possible - you have to include 
pages which contains links to the pages you want to 
download.

You can exclude links, however, like in:
+root.cz/forum/diskuse.php3*
-root.cz/forum/diskuse.php3?*print=1*

This filter will accept all diskuse.php3 links except 
those with 'print=1' in the query string. By combining 
several filters, you may manage to sharpen the scope 
of the mirror
