As far as I remember, the Teletext print function only expects a "dumb" printer connected via RS-232, it never was anything B&O specific. The same function was offered by a number of manufacturers in the early days of Teletext.
Never heard of anybody ever even trying it out, though. Although it would've occasionally been useful, it would've necessitated a dedicated printer connected to your TV, and those cost a lot in those days, so...
EDIT: The product pages have an error, they mention the remote shown here as "V Terminal" but link to the old Video Terminal. The A & AV versions both have their own pages. The old Video Terminal ("Mars bar") is totally incompatible with these.
The page on the A Terminal shows all three of this generation (in low resolution, though). As you can see it is even longer, and totally inconvenient for one handed use!
