MF642 printing to custom paper size

[rodaboyd55]

I'm trying to print to 5.25 x 7.25 envelopes.  I've added this paper size to the printer, but the Print Properties dialogue box, paper size, doesn't list this paper size that I've added to the printer and there is no apparent way to added a custom paper size from the Print Properties app.  Please help.
