The solution is not so straight forward but it is simple trick to get you results.
You will need to open Excel, Numbers, Spreadsheet app and Insert the image you desire into the workbook.
From there you will be able to configure the scale of the printing to ensure that it is 1 page wide and x page in height.
This works on OSX, Windows, Linux etc.. this has to do with how spreadsheet software treat images which are inserted.
