Summary: Only hacks are currently available.

A while back I posted a request for information on printing using
a telnet terminal server from a 4.3bsd host.  Here is the prommised
summary of responses.

Several people pointed out that one can run telnet

Encore terminal servers come with instructions on how to set this up.

a couple of us hacked out a tcp print server to enable us to print from
our sun network on a big imagen connected to a very large apollo ring.

lemme know if you want the code.  it's really quite simple :-)

We do this to 2 LW+'s from VMS & 4.3BSD, talking
telnet to a bridge box in listen mode.  This gives
us connectivity w/o having to rely on any one host
which seemed like a good thing at the time tho' if I
were doing it again, I'd just make VMS talk to lpd
and hardwire the LW+'s  to one of the 4.3 systems.
Works quite well, s/w is home grown.

Encore Corp's Annex terminal server lets you do just this.  In fact, they include
a Centronics parallel port too, in case you like parallel printers better.
They have tons of other features, and I just can't praise them enough.
And people who know me will tell you I rarely give that complement.
They understand the UCB lpd protocol as well.  All very good stuff.
We've tried many terminal servers here, and the Annex is by far the 
best.

cisco Systems terminal servers fully support the use of terminal
ports in the reverse direction (eg host establishes a connection
to a specific terminal port of the server).  Various types of
connections are supported (eg telnet, telnet binary, and 8 bit
stream), along with rotary groups (get the first free port in
a group) and miscellaneous other options.  In fact, we use such
an arangement internally at cisco to allow spooling from our
tops20 and unix systems to an apple laserwriter.  We will supply
source code for a unix filter that sends data over a TCP connection,
that can be used to build full-fledged spoolers, or in a simpler
configuration for smaller networks.

At least one of our competitiors also supports using a terminal
server in ths manner, though of course not as well :-)

Give us a call at (415)-326-1941 if you would like more information.

The Encore TIU (which we also sell as the Proteon TIU) has support for
this.  It requires some changes to the lpd software on the UNIX
system.  The box even has a Centronics printer port, or you can use
an async port.

Roy Marantz here at Rutgers is working on this for lpd.  The printcap
has a terminal server name/ TCP port number entry for these printers.
There is currently still some bug that prevents this from working.

We had several terminal servers for test here. (CS/100 from Bridge
Communicatios, Spider Ports from Spider systems, Micom/Interlan
Terminalservers and an ANNEX box from Encore).
Encore gives you all you want in this direction. Their software is
host based and they have included a patch for the line printer
spooler (at least for 4.2BSD) to use either the parallel port or one
of the seriell ports as a printer port driven from the printer
spooler. You have to add two fields in the printcap file, apply the
patch, recompile and then it works.
Spider systems has a small program in their documentation to print
onto a specified port. This doesn't use the Berkeley spooler, but
perhaps you could use it as an output-filter out for the line printer
daemon.
The other servers don't provide such a feature (or I didn't notice
it).

Hope this helps

I'm one of the software engineers who works on development of the Encore
Annex Terminal Server.  Not only do we currently support both parallel and
serial printers, but we've got some new things cooking for the next release
that will make it possible to run either a bi-directional serial printer
or even a host's getty on an Annex serial port!

The Annexes currently available contain 1 parallel printer port
and 16 serial ports.  Current printer support (for all BSD-compatible
hosts) is by means of either small modifications to the Berkeley
Printer Spooler, or by a program we distribute called "aprint",
both of which are included in source form on our distribution tape.
The Annex operational image (the software you boot onto the Annex
- its loaded from any BSD host on the network) contains a modified
LPD server.  The mods to the Berkeley spooler support a small
extension to the printcap file that allows an annex & port to be
specified as the hardware device.  This is used just like an
"lp=/dev/xxx" entry had been specified.  If you don't have source
for lpd, then you can just use our "aprint" program, which talks
to the Annex LPD daemon and prints (not spools) a file.  An example
of how aprint could be used as a printcap "of=" filter is included
in the administrators manual.

We are currently doing what you want using Encore Annexes attached to an
Encore Multimax. Special case you might say but the same thing can be done
from a Vax or whatever. Robert Claeson  has written
some code to do it. He says that Encore will possibly make it available with
the next release of the Annex UX software. I include it for your info.

The Annex is a nice box and cheap!

What kind of terminal server?  Encore UMAX lpd can drive printers
attatched to Annex printer and terminal ports.  They also distribute
diffs for you to modify your lpd.
