Hi Peter, I think your test was amusing, although hardly conclusive,
unless the only way you read text is via an OCR-reader.

One of the problems comparing printers this way, is that the toners
from various printers might have a different reflective spectrum,
which can influence the way machines read it much quicker then
humans. I've seen ordinary copiers turning output from one printer
useless after copying, due to the toner/exposure mismatch of the
printer.

An interesting experiment is to take output from various brands of
copiers (at least, if they really use different engines, something
which is not always the case), and feed it trough the competitors
version. A good time is garanteed for all!
