It's a raster, printed with the Gimp under Linux. The image
resolution matches the print resolution dot-for-dot (2880 dpi), and
the image is a 1bpp black and white. I've tried single-dot-rows and
single-dot-columns, and pretty much all the settings available in the
print settings block.
Note that enabling bi-directional printing makes it a LOT worse, as
expected - pretty much two copies of everything.
The only thing I haven't tried is producing my own escp2 file for the
printer that uses a single jet in a single pass to see how much of the
problem is physics-related.
