I called Daniel on the phone and clarified some points:

I.E. type:

lpc
disable lw
stop lw
quit

<substitute your printer name for lw above>

. . .

Sort of documented.  I used the following csh script file:
____cut here____
#
# set the Laserwriter IINTX baud rate

cat << EOF | lpr
%!
serverdict begin 0 exitserver
statusdict begin 25 38400 64 setsccbatch
EOF
____cut here____

Cut the above to a file by the name of, say, set_rate.  Then type:
chmod +x set_rate
set_rate

> 3) Change the entry in /etc/termcap to read :br#38400:

/etc/printcap

Sometimes this was necessary, sometimes step 5) alone did the trick.

> 5) Restart the line printer queue.

I.E. type:
lpc
restart lw
enable lw
quit

If you used the kill -HUP <lpd process #> in step 4), to restart type:

/usr/lib/lpd

Here is a file to check your current settings (Postscript material
taken from the Apple LaserWriter IINTX guide, p. 123-124).
____cut here____
#
# get the current settings (status) of the LaserWriterIINTX.

cat << EOF | lpr
%!
/Helvetica findfont 14 scalefont setfont
/cr{show 182 currentpoint 20 sub exch pop moveto}def
/tb{show 300 currentpoint exch pop moveto}def

Treat this in a similar fashion as the set_rate program above.
