Printer Resolution.

Hi. I recently printed the same image twice in an Epson 3880 using Ultra Chrome inks. I printed one versión at 1440 dpi and the other at 2880 dpi. The image it's a 16 bit file. I then proceeded to look at the both images under a microscope at an enlargement approximately 40x. I was expecting to see smaller and double the amount of 'dots' in the print with higher resolution. What I saw on both prints looks very similar (see attached images - resolution in each it's in the file name). I did several treys to ensure no manual mistake. Does anyone have any reference point as to why this might be? Any guidance will be appreciate it. Martin.

It would appear that, regardless of your instruction to print at a higher resolution, the printer selected its own. The only thing I can assume is that your printer is actually controlling the print. Is that what you intended or did you assume your program was in control?

Thanks for your response. The option to define the resolution was set in the print driver from Epson, so I assumed that that's whats driving the resolution. Am I Missing anything? Thanks a lot.
