I'm pretty sure there are non-digital color copiers. I have a color
photocopy hanging in my office that was made at least 20 years ago, and with
the tools available here in the office, I can't see any pixelation. I guess
it could be digitial, but if so, it's a pretty high resolution.
Note that there's no reason a color copy has to be digital. The copier can
still make three (or 4) scans for each color through a filter imaging each
scan onto the drum and printing that color ink in the same way a B&W copier
works for it's single pass with black ink.
What's impressive is how good the copy still looks today. I'm pretty sure
it's a thermal wax print (it feels waxy) which should have good color
retention. It's hung unprotected enough that the white border at the edge of
the paper has yellowed quite a bit, but the reds and yellow are still quite
vivid.
