I had this problem, but careful perusal of the manual showed that the
printer can be reset to 9600 by toggling a switch off, wait a few seconds,
toggling it on again, and cycling power.

38400 will work under 4.0.1 (get the serial patch tape), but not 3.X.
19200 is the maximum speed that lpd understands in 3.X.  They fixed lpd in
4.0, but unfortunately they forgot to fix "tip" (Hello?  Sun?  Hello?).
It still maxes out at 19200.

I have one system running 4.0.1 that has an NTXII, so I tried to set it up
at 38400.  After ten minutes of lpd using 9600 anyway, I was about to pull
out some hair when I remembered that this system supported Interleaf TPS
3.X, and they had required replacing the 4.0 lpd with the 3.X one to work
around a bug.  (*sigh*)  It does work at 19200, though.
