Printing SSRS Reports with Adobe PDF

Sometimes I wondered why after setting up my page size under SSRS properties, Adobe PDF won't show my expected page size in the dialog box. For example if I want to print using "Legal" instead of "Letter" paper size, the Print dialog box shows "letter."

I have found the answer:

According to Adobe Acrobat XPro:

"It’s important to distinguish between page size (as defined
in the source application’s Document Setup dialog box for your document) and paper size (the sheet
of paper, piece of film, or area of the printing plate you’ll print on). Your
page size might be U.S. Letter (8-1/2-by-11 in. or 21.59-by-27.94 cm), but you
might need to print on a larger piece of paper or film to accommodate any
printer’s marks or the bleed area. To ensure that your document prints as
expected, set up your page size in both
the source application and the printer." (Bolded fonts are
mine)

Therefore, after making sure that your property settings selection
shows "Legal" under "Paper size" under SSRS Report
Properties, you then go to the Adobe Application--Print--> on the dialog
box, you will see "Choose
paper source by PDF page size"--> Check this box. This
will allow you to print mixed paper sizes as you wish to set your paper source
in SSRS reports.

NOTE: I am currently using Adobe Reader 9.5 version
