I know how to print  a wrapper to mail a book to a friend, but here is my problem, I ordered a book for my daughter, that just happens to be a wish-listed book, if I post this book to my bookshelf it is immediately going to go on wishlist hold, so how can I print a wrapper to mail the book to her?

You can post the ISBN of a heavily posted book, such as a John Grisham book, and then use the mail it to a friend feature knowing that your actually mailing the wishlisted book.  Hope that makes sense & hope that it helps. 

Have your friend put that book on their own wishlist, then you can go there and post the book to her directly without putting it on your bookshelf first.

If she is a PBS member then have her wishlist the book and post directly to her. 

Or, like I do when I mail wishlisted books in swaps, I add a John Grisham book to my bookshelf and then send the wishlisted book in place of the Grisham book. Just like Sheena mentioned above. Just be sure to adjust the postage amount (if you're using PBS postage) to reflect the book you're actually sending. 

Thanks so much for your help everyone!

You can also do the Custom DC if you don't mind paying for DC.
