Hi Michael,

That is very strange indeed.  There are two selections that my affect this and it
would be nice to know if they help.  For Resolution try 1440dpi and 1440super.
For dither try Ordered and Adaptive Hybrid.   That's 4 combinations but maybe
one or two will be better.   John's suggestion of various input ppi is another
possibility to try.  If the weirdness does show up on a 4000 that would be a big
hint of what to look for.

Unfortunately my 2200 isn't working these days so I can't try the exact same thing.
But send the small file and I can try it on some other printers.
