Re: More pixels negated by printing?

Just look at the numbers. A ten megapixel camera such as the K10D gives an image with 3872 pixels on its longer side.
if this is printed at 300 pixels to the inch it gives an image 3872/300 = 12.9 inches wide.
Most good quality printers can print at 1440 or even 2880 dots per inch, so the printer is using 2880/300 = 96 dots of ink per pixel.
I think the printer is more than capable of rendering an image from a 15 megapixel camera without any problem.
Yep, that's how I'd expect it to be. I think the limiting factor for printers is their colour accuracy and how wide the usable range of tones is between black and white.
In terms of at what point does increased pixel count fail to deliver improvements is surely down to how good the lens is, how noisy the sensor is and what its dynamic range is.
