That's called a "print server" and lots of folks make them (HP,
Netgear, Intel and more).  Some are strictly "lpd" printers: they use
the Unix lpd protocol, and you treat them as though they were a Unix
box with an lpd printer attached.

Others are port printers:  anythin g presented to them at a certain tcp
port will be printed.  The port used will vary: HP uses 9100, Netgear
uses 4010 and others use others.  For example, if you "telnet hpjd
9100",  anything you type will print.  I have a listing of some at
http://aplawrence.com/Jeffl/portnumbers.html

For example, I have a Netgear PS110 here at 10.1.36.221 and I
configured it on Mac OS X with

sudo lpadmin -p laserjet6L -E -v socket://10.1.36.221:4010 -m laserjet

That defines a printer "laserjet6L" and tells it that it should send to
10.36.221 on port 4010, translating postscript to laserjet.

Many of these are multifunction.  For example the Netgear PS110 (a two
port model I use a lot) uses the port method, but also can be a lpd
printer, a Novell style ipx printer, and a Windows SMB style (iow, it
appears in network neighborhood).  The nice thing is that you don't
have to choose: you can use all the protocols at the same time.

BTW, the HP print servers (not the MIO cards) will happily print to any
parallel port printer, though some older models didn't understand the
newer style EPC ports.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
