worth asking but file with the color copy since you have to apply by the 11th. If they reject it on the grounds that a hard stamped copy us needed then they will probably give a few days to correct it
make a new post with the your details. Here is mine for example. You can copy paste and edit your experience, office, country or origin and visa type so we can all learn.
printed a color copy from email. No idea if that's 100% valid or not since no americans have reported if they went from under consideration to an extension yet, but the color copy was accepted at muang Thani for an under consideration stamp. Rules will vary by which immigration office serves your area.
