Im new to printing and all these terms from printer specifications are extremely confusing; dpi, ppi, dpp, amount of colors, droplet size, etc. Why is the maximum dpi on printers decreasing and droplet size increasing? Isn't that a downgrade? How is it that a printer like the Canon image prograf 1000 has only a resolution of 2400x1200 and a droplet size of 4 but an older printer like the Epson r3000 has a vertical resolution of over 5000 and a droplet size of only 2. Isn't that a downgrade from the Canon?

I am looking for a printer with color accuracy as close as possible as the image being printed and the ability to print VERY VERY small and fine text, as close to "microprint" as possible. The image being printed is a scan of a document. The total resolution of the image is 4409x2425. The microprinting is so small that it can barely be read without a magnifying glass.

Im really confused by what to look for in a printer for my use or how the specs work in general. There seems to be very litrle explanation on these and the few I have been able to find all differ from each other.

    I'm afraid that "best quality" for most photographic purposes will be very different from the "best quality" you are looking for. It appears you are interested in greatest apparent resolution of high-contrast fine detail. For "best quality" for most prints, tonal range, color reproduction, longevity, and other concerns usually outweigh this particular focus on ultra-small details in the print. – mattdm Sep 22 '18 at 21:21

    Is this another question about how to "print currency?" – Michael C Sep 23 '18 at 3:21
  • @MichaelClark what's this about currency printing? – Hueco Sep 24 '18 at 20:21
  • We tend to get questions periodically that seem to be asking how to print things that sound suspiciously like someone is trying to print money or other negotiable instruments. This looks like such a question to me. – Michael C Sep 24 '18 at 20:22

    @dandavis Please read your comment and correct the contradiction. – Stan Sep 25 '18 at 17:55
