Impact, not thermal
The right supplies for the Okidata Microline 420
Two consumables: forms + a ribbon.The Okidata Microline 420 is an impact printer — it strikes an ink ribbon against multi-part carbonless forms to make copies. So you buy both the continuous forms and the ink ribbon. Thermal paper has no ink and prints blank; pin-feed (½" sprocket) tractor holes are standard.
