Laser printers are purely b&w and produce shading by halftone dithering.
Eink displays are grayscale. 16 shades most commonly.
For a laser printer to produce 300dpi/16 shades like today's eink it would need to go to 1200dpi.

A 600dpi grayscale eink display would be comparable to commercial offset lithographic pbooks. Pretty clearly overkill and not worth the higher cost required.
