I've succeeded in making the LaserWriter+ work from a Sun-3/50 running
SunOS 3.5 and Adobe TranScript 2.1.
The cable is simple:
SUN workstation (3/50) LaserWriter
SUN workstation (3/50) LaserWriter
gnd (7)------<----------------------->-----(7)
RxD (3)------<----------\ /---------->-----(3) RxD
X
TxD (2)------>----------/ \----------<-----(2) TxD
/etc/printcap is also straightforward:
# local PostScript printer driven by TranScript software
lp|applejuice|lsmlaser|ps|postscript|PostScript:\
:lp=/dev/ttya:sd=/usr/spool/lpd:\
:lf=/usr/adm/lsmlaser-log:af=/usr/adm/lsmlaser.acct:\
:br#9600:rw:fc#0000374:fs#0000003:xc#0:xs#0040040:\
:mx#0:sf:sb:\
:if=/usr/lib/ps/psif:\
:of=/usr/lib/ps/psof:gf=/usr/lib/ps/psgf:\
:nf=/usr/lib/ps/psnf:tf=/usr/lib/ps/pstf:\
:rf=/usr/lib/ps/psrf:vf=/usr/lib/ps/psvf:\
:cf=/usr/lib/ps/pscf:df=/usr/lib/ps/psdf:
Here is the tricky part: my LW+ was doing DTR flow control rather than
XON/XOFF. To correct this send the following PostScript to the printer:
%!
serverdict begin 0 exitserver
statusdict begin 25 9600 0 setsccbatch
I found this in Appendix C of the LaserWriter IINT manual, and out of
desparation tried it on the LW+ with favorable results.
Thanks to all who responded to my question.

I had also a bunch of problems getting the &$#@#@$&mned LaserWriter
printing properly.
I hacked some wiring problems with DTR:
The standart flowcontrols from transcript can be used with the following
cable:
SUN LW
2 ---------\ /--------- 3
X
3 ---------/ \--------- 2
4 --+ +-- 4
| |
5 --+ +-- 5
7 --------------------- 7
A while agoo i saw a small PostScript program to fix the problem but i
cannot reproduce that program ( I'm not a great postscript expert ;-( It
was some serverdict bungling....
Hope this will solve your LW+ problems....
