What we could suggest you in order to achieve the desired is to use the MinTimeRulerExtent
properties to modify the size of the RadScheduleView
to fit the available area.Then you can to print the updated RadScheduleView that visualizes the appointments as expected and after that returning it to its original size - thus the ScheduleView will be printed with bigger measures and the appointments could be visualized clearly as desired.
Please, check that attached sample that demonstrates that approach.
Hope this helps.
