Thanks for all the responses. My original posting was:

What turned out to be the correct answer (but not actually the
solution) came from who clued me into the
correct entry in printcap of ms=crtscts. (The printer daemon
ignores the eeprom setting of ttyb-rts-dtr-off=false.

When the LaserWriter is configured for RTS/CTS handshaking,
this printcap option seems to do the trick.

The problem was worse than I thought, however. The PC's and XT's
that were also using the LaserWriter via a switchbox insisted upon
ETX/ACK handshaking (Don't ask me why. I don't DO pc's.)
Fortunaltely of the four settings for handshaking on the NTX,
(one for RTS/CTS, one for ETX/ACK, and two for XON/XOFF) one of
the XON/XOFF settings seems to satisfy the PC's too. (Probably does
both and confuses everyone.) Anyway the user is happy now; and
I am placated.
