Why do you assume there even IS any raw tcp feature?

The dlink web site and some user reviews on shopping site both imply that
it
supports LPD and neither mentions raw tcp on any port nor uses the term
jetdirect anywhere.

Agreed, however, this turned up in a search:

http://aplawrence.com/Jeffl/portnumbers.html

The comments at the bottom mention D-Link multi-port print servers and
ports 9100, 9101, and 9102.

Good find, however, features that exist but aren't advertized, even deep in
the fine print, are also just about garanteed to be almost untested.

If it works, fine, if it works but is flakey or locks up or fails in any
other way 5 times a day, or worse 5 times a month (because then it takes a
lot longer to figure out), oh well you're using a feature no one promised or
even implied would work.

We should try to compile some more columns on a table like that which
provides success/fail reports from real users in decently heavy production
environments. Not merely that the feature exists, but that printing x pages
per day from x number of users and it never needed to be power-cycled. per
protocol and per firmware and/or revision. The cheap units often may be ok
reliable using netbios and/or lpd, but lock up several times a
day/week/month using netcat. Whatever protocol the windows install
directions for a given unit describes, _that_ is the only protocol that gets
99% of the testing and firmware fixes, which may be as little as netbios and
nothing else even if it does have appletalk, lpd, raw tcp etc.

I don't even want to think what a $45 linsys/netgear ps101 cost a few
different customers where some other genius (not me or anyone in my company)
put them into critical positions.
