The Linux version of Eclipse doesn't support printing. The alleged reason is that printing is so flexible in Eclipse that no one could agree on a suitable subsystem, especially considering that the Linux version has 2 different graphical toolkit versions (gtk and motif).
The way around this impasse is to use the Tools menu to define your own print tool of choice. The simplest one, of course, being just to run the lpd program on the currently-selected file.
Some people, when well-known sources tell them that fire will burn them, don't put their hands in the fire.
Some people, being skeptical, will put their hands in the fire, get burned, and learn not to put their hands in the fire.
And some people, believing that they know better than well-known sources, will claim it's a lie, put their hands in the fire, and continue to scream it's a lie even as their hands burn down to charred stumps.
