#2255 — Portable text2eth0 printer?

Presently I use rPi to listen to text-to-speech, by transfering the PC
generated *.wav files via a USBstik, to the battery-powered rPi.

Similarly, instead of finding some Windows-user, to print my text via
their eth0 connection, I want to just plug my battery-powered rPi into
the office ethernet that feeds the printer, and get the text on the
USBstik, printed.

The rPi will be hearderless: without any display + keyboard;
like when it plays my text-to-speech files.

So then I'd need to find out the printers IP?
How do I do that?
The 'one' user who may co-operate with my needs, would not know.

Perhaps the HP-printer's name is standard for the product, and
available via the net? But no; since it must be able to share
the ethN with other same-make printers?

What's the general syntax to drive the printer ?

== TIA.

You can always use ssh to log into the rpi from another computer, and
use its keyboard and display.

Is it the same always or does it change?
You do not want to be changing the setup each time you do it, as you
also then need to install the printer ppd file, edit /etc/cups/printers
etc.
What kind of printer is it?

you tell us nothing about the printer.

No. I listen to the battery-powered-TTS, lying-down, at a location with
no electric supply. Similarly, I want to be able to just bring my
portable rPi to the eth0 And get printed paper.

I was thinking 1980's: you give a strean of bytes, and get the paper
printed. Perhaps it's easier to just fax the text to the printer/fax
combo?

If the printer has serial or parallel connection maybe you could do that.
Ethernet is shared wire with packetized protocols. You can't just spew
byte streams to it.

Your rPi will have to be configured with an IP address appropriate for the
network with the printer. Hopefully the office has DHCP server so the rPi
can auto-configure it's network settings. Once on the network you'll need
the IP or hostname of the printer as well as the type/model ("HP" is not
enough). Use that info to configure lpr or cups on the rPi. Once all
that's done you can print with "lpr filename" or similar.
