To my knowledge only laser printers participate in the MIC scheme. While the boundaries of the program are somewhat unknown, just from a technical perspective inkjets generally struggle to produce low enough coverage for the marks to not be pretty visible to the eye (bleed of inkjet inks prevents high-pitch halftoning performed by laser printers to produce very low coverage).
