Aside from RISO's SF5130, all of their duplicators now come standard with a network card for network printing. However, printing from MAC OS requires ordering a Mac Driver which requires a license key ordered from RISO - doesn't cost anything to order.
Also, RISO's Mac Drivers are always behind with current Mac OS versions. They haven't released a driver compatible with OS X 10.15 even though it's been about 6 months since 10.15 was released.
Sorry I'm late to the party.
