Printer printed sideway

Hi All, I am using a brother printer J5720DW, For some reason it has started printing sideways, after reading through these threads & other searches I have checked to make sure that it is on portrait and it is. It prints landscape style no matter which is checked. I have removed all the printer software and then reinstalled the software and printed out a test page, and still printed side way and small. This has been very frustrating using all this ink just trying to fix the problem. Any help would be greatly appreciated.
