Digital BW, The Print

Try viewing the image at the pixel level and slowly pan through the cloud, making note of the exact pixel colors as you go. You may find that the image itself has banding -- unseen on a normal-sized screen image -- where the pixels colors show large leaps, as you scroll down. This can happen when the visual graduation of the cloud is more subtle than your processing program can handle. An easier way to check this is to add a bit of noise to the cloud on a copy before you try another print. 

Banding of this kind is more common than you might think, and has nothing to do with the printer.
