That is what I don't get. If 4pt gives you 130 lines per page, you would only need to fit 20 chars per line to fit the entire thing on one page. With 2560 chars on 11 pages means 233 chars per page at 130 lines per page, we end up with roughly 2 chars per line.

We already know he was basically giving them the middle finger by printing it AND printing it very small. He would clearly need to do something extra odd to make it do this.

You can see how he did it on the court documents (it's attachment A on page 145-150).

He might have done some less efficient encoding, like Base-16.

And that's only 6 pages... it looks like he printed it in 11 columns spanning 5.5 pages...

I think the court documents have two pages per page.

But still very much illegible.

He could have been "helpful" and provided ancillary information along with the keys.
