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 printer's 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.
