As far as I know there is no way to print a list of only your wants and haves for a single player / team / set. The only way I have figured out how to see a list of wants and haves is to create a collection for the player/team/set with the cards you have and the cards you want and then go to your your account name in the upper right and select Collections. Then select the collection you want to view and click CARDS. Then choose the appropriate sport. You should then get a list of all the cards you have in that collection. If you choose ALL in the drop down menu in the upper right (and only have cards on a wantlist and have-list) you will get a list of your wants and haves ordered in the sequence the database sorts them in.
Note this will not include Multi-sport cards. From there you should be able to copy/paste to WORD or save the page as a pdf or something to get a printable list - but that is the only way I have figured out how to do this.
