%The entry for the Epson.JX-80 says:
%
%"The "Epson.JX-80" printer definition file is the same as the "Epson.FX-80"
%file, except that it uses colour for non interlaced graphics printouts ie.
%120 by 72 DPI or lower. There are two reasons for this. Firstly, interlaced
%colour printing would involve an excessively large number of  print head
%passes (8, 12, 16 or 24) over the same line on the paper. Secondly, on the
%second or subsequent interlace passes, the light ribbon colours (eg. yellow)
%would be printing on top of dark colours already on the paper. This causes
%contamination of the lighter ribbon colour and seriously reduces usable
%ribbon life - unless you are happy with muddy yellows."
%
%This explains why I didn't put colour interlaced resolutions in. In a school
%environment (and many others), it just isn't appropriate as it takes forever
%and destroys the ribbon in no time at all (and schools can't afford to waste
%consumables like that). Kids being kids, it is very likely that left to
%their own devices they'll select what appears to them to be the best
%resolution ie. the highest.
%
%As to what you can do about it, all you need to do is play around with
%!PrintEdit for 10 minutes. I did actually try 360 by 360 colour on a Star
%LC24-200, starting with a brand new ribbon. It took FOREVER to print (16
%head passes per line) and the paper was a soggy mess afterwards. The 180 by
%180 printout of the same picture actually looked better. (There was a review
%of colour dot matrix printers in Acorn User about 18 months to 2 years ago
%that said the same thing ie. 180 by 180 looked better than 360 by 360.) On
%top of this, when I tried it the ribbon needed changing after just one page
%of 360 by 360 - the yellow just wasn't yellow anymore after over-printing so
%much on darker colours. I stand by my decision not to make interlaced colour
%resolutions available in the supplied printer definition files. If you want
%to add it yourself, go ahead. !PrintEdit is all you need.

Why not just print the yellow first? This seems obvious to me.
