Nitpicking:
"Dithering" in raster graphics is emulation of color resolution at the
expense of space resolution.

The fuzzy lines are rather the opposite. They use surplus color
resolution to emulate ibetter spacial resolution. Over here the usual
term is "Anti-aliasing".
I admit "dithering" may be incorrect term, but I am in doubts if that
printer (claimed to have 300dpi resolution, but not suitable for QR
codes) has surplus color resolution. I do not mean anti-aliasing in the
sense of adjusting pixels darkness (and color).
Consider 2 squares having size of 2.5×2.5 pixels. Non-even sizes and
fuzzy lines variants:
███ ██
███ ███
███ █ ██
██ ██
██ ███
Second variant might have sense if an image is treated as a photo
unlikely having regular patterns with horizontal and vertical lines.
