In Figure 1, a technique/device 10 for delivering toner 12 directly to paper 14 is shown for use as a possible printing engine. The technique involves sandwiching paper 14, preheated by heater 28, between a magnetic marking material or toner 12 on a supply roll 16 and an array of pin size electromagnets 18 which will be referred to as the magnetic record head 18. When these magnets are turned on, magnetic marking material will jump to the paper and will tack. The array can be switched by an Electronic Support System (ESS) to complete the printer scheme. Any suitable fuser (not shown) added downstream from the transfer area 20 would complete the printing process.
