Google Photos will allow customers to access same-day prints from either Walmart or CVS -- the new service will also extend t prints and canvasses. Google has also indicated that it will work with Walmart as well CVS in order to create same day pick up for the photos, or for the other three day print times. The photos will be available on 4x6 prints.
The same day prints are not currently available on Google Photos. However, the new feature will most likely be inside the "Photo books" section of the navigation menu, the section could be referred to as "Print store."
Both Walmart and CVS have same-day photos printing services already, however adding the feature into Google maps could offer more convenience to customers.
