Hmm, it might be. Thanks for pointing that out.
The positive thing is that, because it is a constant object that's on the card and very different from the dots, I believe the mind will figure out very soon that it should be ignored. But the point you make remains.
We didn't have dots in mind when designing the printout function. We only imagined pictures, in which case a logo and a small print of the word name at the bottom (it's not a page number, btw!
) would not be distracting compared with the picture (of for example, a dog).
Will have a further think about this!
