This looks much like that the data coming from acroread is already bad
quality.

Sorry, I have overlooked the special case for acroread. acroread sends
jobs in PostScript format AFAIK and due to DRM (Digital Rights
Management) problems we do not convert this PostScript into PDF,
regardless whether the printer is a PostScript printer or not. So only
the pstops CUPS filter will be called. And this means that no graphical
elements of the original input are turned into bitmaps (rasterized) and
so if some parts of the printed output are bad quality, this bad quality
must come already for the input.

So I fear we are hitting a bug in the Adobe Reader (acroread) here.
