[GreenKeys] M28 printer FIGS-LTRS weirdness

[Nick England]

The space after the overprinted FIG appears normally, so all I have
hypothesized so far is that the hammer is striking the # as the typebox is
shifting right from FIGS to LTRS position. I need to experiment some more.
I don’t think it has anything to do with ITTY. A quick test with a keyboard
also overprinted.
