A family of Microsoft word processing software products for creating web, email, and print documents.
If you open the PDF in Adobe Reader and press Ctrl+P to open the Print dialog, you should see, on the right, an image of your document that shows the defined size of the document and the default paper size. The example below shows an 11" x 17" document with Letter-sized paper selected.
In order to print this document on Letter paper, I would have to choose "Fit" or "Shrink oversized pages" or "Custom scale." But I can also click Page Setup... and choose a different paper size.
If I choose "11x17," the document fits without scaling. As it happens, my printer can't actually print 11x17, but I could send the PDF to a printer that could. The size you would be looking for is perhaps listed as "Statement." If you don't find it with your default printer selected, choose the Microsoft XPS Document Writer, which does list this size. Once you've created the PDF that size, you should be able to print it from your default printer (if your printer can print that size).
