Just bought an Olympus mju mini for work. It's small, has flash, digital and optical zoom, a million program modes and is weatherproof, perfect. To go with it I have bought a dedicated photo printer for producing 6x4 prints which I can attach to paperwork for onward submission to my customers. Given the plethora of resolutions on this camera, what would the best res be for prints this size given that I want to maximise the number of shots I can take? Is there any advantage in taking higher res shots for 6x4 prints? I've checked the beginners sticky but it doesn't really answer my question. By the way, if there is a table available of ideal image resolutions for a given print size I would be grateful if someone could point me in the right direction.
