.Net Join small pages missing in print options

[fkbeys]

I m trying to join small pages . But in .Net version, there is not a option for it. But in delphi version, it Is usable. If the design file is Fr3, the join small pages option is visible. On the other hand, if the design is frx, the join small pages option is invisible. how can i solve this issue? I need to join small pages into one page.
