Change Orientation of Label on GX420t

I have an application that prints labels that are 2 1/4" wide by 1 1/4" high.  I would like to print the same report on a label that is 1 1/8" wide by 1 1/2" high. I have tried to change the orientation in settings but it does not seem to work.  How can I get the report to print on the new label?
