I have a very simple question about how to use lpr to print to
a network printer. This is probably staring me in the face in
the man files, but nothing I try seems to work, so I'd
appreciate a boost.

I have a printer with an ethernet interface and IP address
192.168.1.29. I have some Linux and OS X machines here but
I don't have Linux or OS X drivers. But I don't need to do
more than print tickets with a few characters. So I just want
to send text files to it and see if that's good enough.

So my question is how do I send a text file to this printer
using the lpq system? What tool do I use to create a print queue?
How do I send the file to that queue?

Thanks
