Continuous Sets the continuous numbering mode: 1,2,3 etc. (not 1,12,34,57 etc.)
Odd and even separately Sets the numbering mode in which the page numbers are like this: 1,3,5,7 or 2,4,6,8 etc. You may find this mode useful, for example, if you scan many double-sided pages - first you scan the odd side, then you scan even side.
