Fix pagination in stc sample

Browse Source 
1. Fix setting page size if printing is done in the landscape mode.
2. Store ranges of printed characters for all pages (not only recent page)
while doing pagination (in GetPageInfo) to allow printing pages (with
OnPrintPage) in any order (not only sequentially).

Closes #17107.
