I have 3 comments to add to the previous reply & recommendation.
1. I'd change whichever switch setting is less used, probably the 1200 port.
   (I'm pretty sure it can be changed, but I didn't look it up today.)
2. There may be a program function for autobaud 300-38K, It is implemented on
   at least one postscript printer, but possibly not the apples
3. If you are using a ibm pc, there are local-(apple)-talk boards available.
   One of these would be fine if it will work with your software.
4. You could use the functions of (semi-)-high speed network between ibm's &
   Macs & use a mac as a print spooler & appletalk comverter. Either with a
   laser NTX, or like a Tops & novell net.

In any case, I'd definately try a higher baud first & try my best to live with
it.  All of the other 3 have some (almost serious) drawbacks to consider.
