I have learned that Te Oku means "to do something in advance for preparation".
However I have encountered this sentence :

> その紙は いらないのですて **ておいて** ください  
>  This paper is not needed, please throw it away.

I dont understand why Te Oku is used here.  
I wonder if Te Oku has another meaning. Is that right ?

question
grammar subsidiary-verbs
besides meaning of preparation, what is other meaning of Te Oku
ておく can mean, as you said, "to do something in advance for preparation", but
it can also mean "leave it and pay no more attention to it", depending on
which verb is used. The latter applies frequently to the class of words that
already inherently have to do with not giving something any attention anymore:

Examples of the latter category:

* * *

  * **ほっておく**

> 主な英訳 leave、leave alone、leave behind、leave

  * **捨ておく**

  * **忘れておく**

> ～のことは忘れておく let ~ go hang〈話〉

answer
Nice question. Your understanding of ～ておく is correct. I looked at [this
source](http://japanesetest4you.com/flashcard/learn-japanese-grammar-42/), and
found that their translation was "do something in advance." I totally agree
with that from my personal experience.

Your example sentence is a great example sentence. You are right to question
"what is this being done in advance of?"

You could easily say:

> その紙はいらないのですててください。

and have the same meaning when translated into English. The Japanese, however,
is different in feel, not necessarily in translation.

The difference here is the implication that comes with it. I'm going to take
the translation you have, and add in parenthesis the implication. Hopefully
that will help clear things up.

> Because we don't need that paper, please throw it away (so we won't have to
> later).

We are throwing the paper away in advance of needing to throw it away later.

You asked:

> I wonder if Te Oku has another meaning. Is that right?

The answer is no, there is not another meaning of ～ておく. In this sentence, it
is used correctly, just maybe counter-intuitive at first.
