when printing A2

[mart77]

sort of a printing question, when you print a print at a2, all other things being equal, will you see much of a difference if the original file is 10megapixel vs 20mp in the print itself?

Slightly. You'll notice that the 20 has sharper edges but 10mp overall isn't too bad. On a 40x60 inch print you'll notice that a line can be spread over several DPI if done at 10mp while 20 will even that out more and look crisp, colours won't wash too much either.

This is from my experience using my Z6200 and DJ800 printers though
