Printing to serial port?

[Adam C Powell IV <hazelsct@mit.edu>]

Greetings,

I have a StarMax (Pmac 4400 clone by Motorola) with a LaserJet 1100
connected using "PowerPrint", which is a mac serial to parallel
interface which comes with MacOS driver software.

How can I print to the serial port?  I tell printtool to use device
/dev/ttyS1, and when I print, it says:

# lpq
lp is ready and printing
Rank   Owner      Job  Files                                 Total Size
active root       0    /usr/share/printtool/testpage.ps      16399 bytes

But nothing happens.  Here's the relevant /etc/printcap entry:

##PRINTTOOL3## LOCAL lj4dith 600x600 letter {} LaserJet4dither Default
{}
lp:\
 :sd=/var/spool/lpd/lp0:\
 :mx#0:\
 :sh:\
 :lp=/dev/ttyS1:\
 :if=/usr/share/printtool/master-filter:

(no replies from debian-ppc list, so I'm posting here.)

TIA,
