Blu-Tooth printer and Droid X

[PTraverse]

I've found a great print app from fellow members to use with my Droid X called Print Share. Thank you very much for the help.
Now if any of you have the Droid X and are using this app via use of a BT Printer, could you be so kind to share what make and model you have. I am looking to purchase one and want to make sure i get one that is compatible.
Thank you in advance
