Going on the information of Dirk Rijmenants and other locations on "the
intertubes", the KL-47 was the name for a KL-7 with attached five-level
reader/punch. The straight-up KL-7 did print to tape though.

Speaking of Dirk Rijmenants and his page, you can find it here:
http://users.telenet.be/d.rijmenants/ Where you can also find a nice
simulator of the KL-7, as well as pages on aforementioned numbers stations,
OTP, a simulator of the German Enigma, the US M-209, the Hagelin CX-52, and
more.
