saving excel as pdf

Hi I was using the following lines to save my excel file to pdf for landscape orientation. I can save the file as pdf but the printed pdf is not in landscape setting. Any suggestion is appreciated. Could anyone please take a look how i could it set for landscape orientation. Thank you very much:

hExcel = actxserver('Excel.Application'); hWorkbook = hExcel.Workbooks.Open(sprintf('%s','C:\Users\Mohammad\Desktop\test.xls')); hWorksheet = hWorkbook.Sheets.Item(1);

hWorksheet.PageSetup.Orientation = 1; hWorkbook.ExportAsFixedFormat('xlTypePDF','C:\Users\Mohammad\Desktop\test.pdf');
