Dot Matrix Orientation

Currently I am working MS-Reporting Service to generate a report that will be printed on a dot matrix printer SEDCO Ultima 90 .

I have pre-printed form which is on “landscape” (15×8 in) and the paper input is as such and I adjust the layout page size and the interactive size to be the same as the page.
During printing, if I choose to print with “landscape”, it prints out as another way round, i.e. portrat (the printer prints 90 degree rotated text), if i print it to be portrat, then it’s printed normal but i will have a problem on adjusting my document!

I am not sure if anyone faced this problem before, I even tried to change my printer orientation setting in my windows but it’s still the same.

Appreciate a lot if anyone could share on this. Thanks
