The serial ports on all Sun 3 motherboards will reliably do 38400 baud.  When
I used to work with Suns, I ran our LaserWriter at 38400 baud without
a hitch through the Sun-supplied printer cable.  Of course, if your printer
is located a good distance from the 3/60, you may not be able to use the
higher baud rates.  Try it and see.

As for screwing up the baud rate:  the program to change the baud rate
needs to be sent to the printer only once, as the information is not stored
in RAM.  If you are careful I doubt you will have any problems.
