Well the scanner claims 4800 dpi optical, so that's 1.6GiB per page.

(Actually the scanner claims 4800 x 9600 dpi optical  but I can't see 
how to ask it to do that).

So there's a question of what's practical. I only have about 4Tib of 
free space, so that's 2500 colour pages at most.

It's also incredibly inefficient: that same information, if it had been 
born digital, would take 100kB per page or so.

I've not tried opening a 100GiB document lately but I assume that any 
PDF reader will some issues.

Neatly solved in the document's future (but our past and present) by 
having documents that are born digital.

That just leaves a few hundred years of printed matter to deal with. 
Luckily noteshrink seems to do a good job.
