Reporting Services - Orientation Paper - Widht - Height

Question

Hello Guys.
Have you seen that when the Widht is bigger than height, the SSRS change the orientation paper to landscape and in the another way it changes to portrait?
I have a paper who has more widht than height but I want to print it as portrait, because It will be printed in a continuos printer and the size of each paper is like an envelope.
I Have been looking for a solution on internet about this issue, but I havent found anything. 
For example. one Guy has the same problem and he wrote this: (I know is nothing about the printer, the problem is in the configuration of SSRS.) Thanks in advance!
I've come across what appears to be a bug in SSRS. If after reading this post you feel otherwise, please reply to this thread...
I am trying to use SSRS to print to a Dymo LabelWriter 400 printer. This is a specialized label printer that prints one label to a page. The label paper I am using 2-1/2 inches by 1-1/2 inches. The Dymo printer
driver prints portait layout as being the 2-1/2 inches width and 1-1/2 inches height. I assume that is because the paper rolls through the printer that way and labels normally are printed with more width than height.
Other software programs I use to print to this printer handles it properly (Microsoft Word, Microsoft Office Document Imaging, Dymo Label software). However, SSRS seems to assume that portrait layout must
mean paper height > width, as there is no explicity setting in SSRS to for page layout. The result is that no matter how I layout my SSRS report (e.g., switch width-height values, use tb-rl to rotate text), SSRS makes the final decision on whether it is
portrait or lanscape. And in this case of the Dymo printer, it always sets it to the opposite of what it should be. Changing the printer settings (whether default or whether in print dialog) does not correct it.
Although assuming that portrait layout must mean paper height > width may seem to make logical sense, not every printer works that way; and other software programs (including Microsoft Office) do not make that
assumption. It seems that SSRS and/or RDL spec should allow one to explicitly set portrait/landscape setting and not care about width-height ratio. It should be left to the printer and printer driver to decide.
Have other people come across this issue, either with Dymo printer or in other context? Were they able to find a workaround?

Hello Jin-
Thanks for your Answer.
I already added my Service Reference. But when I tried to use the code that you gave me, 
the class ReportExecutionService rs =
new
ReportExecutionService() could not be found.
I am forgeting something?
I added my code. Thanks again!
