Using 2d barcodes you can fit ~20MB per page. Front and back you could probably fit a model that violated the rule on less than a thousand pages. Edit: maybe 1

  Skip the barcodes - just cast it to 24bit RGB data, add in some error correction, and print as a high-DPI bitmap (or a series of them, one per page).

    Printers that can keep all the color channels lined up all the way down to their tightest dot pitch are few and far between. That is why piql used black and white for the boxing code they used to print out all of github. I'm not sure why greyscale wasn't used.

It only takes few to establish a service. Spatial and color accuracy is going to be a challenge, but I imagine there already exist methods to correct for that - e.g. printing reference patterns along with the data, so the scanner/digitizer can calibrate to it on the fly.

  I’m doubtful that barcodes would qualify as free speech.
