Do you want to change the orientation of your screen or write vertical text like this

For the former you’d obviously use the respective feature of the display library you use (which we don’t know without you telling us) and for the latter I’m not positive there is a direct option.

To be exact, you are not printing vertically but rather rotate the screen orientation from portrait mode to landscape mode - for that reason you cannot mix text orientation as the screen only has one direction at any given time.
