When I export PDFs of documents set to "document/letter" in page setup, the resulting download is not formatted to print 8.5 x 11 and has to be "shrink to fit" in the print dialogue. The file that comes out is usually 12.5 width and 16.1 or 16.5 length (it varies). I've tried multiple settings to see if I can figure out why it's doing this, and I'm stumped.
