.rdlc Report print when width is more than height automatic landscape mode

Problem: I am using the printer zebra LP 2844 to print labels that I created in asp.net as microsoft Report. The Report has the size: width:7.5cm and height : 5 cm. when I use the print button in the microsoft report viewer it automatically sets the orientation to landscape mode switching the width and height ==> width:5cm height: 7.5 cm. this causes the report to be prints vertically using 4 labels instead of 1. Any proposed solutions, or did anyone face this problem before, if yes I would appreciate any help.
