Financial terms of the deal were not disclosed.
HP, the world's No. 2 PC maker, bought Snapfish for more than $300 million in 2005 and made the company a part of its printing and personal systems group.
Reuters had reported in September that HP was exploring a sale of Snapfish.
HP said in October it would separate its computer and printer businesses from its corporate hardware and services operations this year.
