[Inkscape-user] Printing Windows

I am on Windows Vista with an Epson3800 printer Inkscape document properties show the width at 22 x 17 in When I File->Print I set the printer to Epson3800 then use Preferences to set the paper size to 17 x 22 in and orientation to Landscape. The printer prints only the upper left 8.5 x 11 in and crops off everything else. How is it possible to print documents larger than 8.5 x 11 in? Thanks, Howard
