The big problem you have here is that your aspect ratio is wrong. A0 (or any other A size paper) has an aspect ratio of 1:sqrt(2) or 1:1.414 or so. Your image has an aspect ratio of 2048/1152 = 1.777. You're going to have to decide whether to crop your image, or print it "letterboxed". Other than that, see the question linked by mattdm.
There is a looseness or imprecision in the general use of terms like EV and LV that are leading to some confusion here. So first we need to use consistent terminology and labels to unravel this. EV is a relative number, independent of any concept of ISO. There is no ISO anywhere in the EV equation. This agrees with the Wikipedia article on Exposure Value: ...
EV, Exposure Value, is used to summarise the two camera settings, exposure time and aperture, in one value. Cementing the idea that there are many pairs of exposure time and aperture that yield a given exposure. If the ISO used is known, or assumed, typically ISO 100, then the EV is directly related to the lighting conditions. Sometimes this is shown as ...
