Comment 3 for bug 155935

How do I do Transparent or pass-through printing (slave printing)?
Many terminals, and just about all terminal emulators, have the ability to do "local" printing. It's sometimes called "transparent printing" or "pass-through", but the idea is that if the terminal sees a special key sequence, it will start sending the data out some other port (parallel or serial) until it sees some sequence that tells it to stop.
You can find the start-stop sequences in /etc/termcap: PN is the sequence to start local print; PS is the sequence to stop. For example, if you look at the vt100 entry, you'll see:
:PN=\E[5i:PS=\E[4i:\
If you have a graphical printer on the linux lan, you can print the text file by ( for example ) gtklp program called by gnome-terminal!!!.
I hope this is more clair.
Thank you.
