BSD doesn't do LocalTalk either as far as I can tell. The StyleWriter 
apparently expects to see 57.6K by looking at Monroe's documentation on 
the lpstyl filter/driver he wrote.stty says that my ttyS1 device has its 
speed set at 57.6. I'm running the 2.2.18 kernel and don't know what the 
max baud is for sure.

I found a good resource on linux printing: www.linuxprinting.org

It suggests using PDQ rather than lpr and has a good setup using 
Monroe's lpstyl driver/filter that I am attempting to set up and run as 
I type. If that fails, I may be asking you more about debugging things 
via the null modem technique you suggest :)-- that is, if you're willing.

This appears to be something I need to install ("command not found"). 
Can you elaborate?
