Macrofying Captures a Printer Laying Ink onto Paper in Extreme Close-Up

A Printer Printing onto Paper

The account @macrofying posted a macro photography series showing a printer at work: ink droplets landing on paper to spell "macro," a printhead injecting droplets, a single dot forming beside a finger for scale, and finally the printer printing a picture of itself. The thread also covers how the rig was built, and commenters say the images belong in science and children's explainer books.
