[Sunhelp] Serial PS line printering on 3/260 crate?

[BSD Bob]

Anyone have any leads to info on serial printering with an old 1200 baud
Postscript printer (EARLY apple lj1 thing) on a 4/260 class machine running
SunOS 4.1.1U1?  I am using one port as the console.  There is a second
serial port,  and if necessary, I have a spare printer/serial I/O card 
that I could bring up in it, provided I can find the right bus/card/slot
jumpering.  Any insights are appreciated.

Thanks

Bob
