I'd very much recommend a second-hand Epson TM-M30 if you can pick one up for cheap. It prints at 203dpi and can output true grayscale (multi tone) without dithering.

Error diffusion dithering should be done in linear color space to avoid the severe increase in perceived lightness of the dithered image.

See https://surma.dev/things/ditherpunk/ under "Gamma" for more info, and some example gradients that clearly demonstrate the effect.
