Printheads
Hight Speed Thermal Printhead (8dots / mm)
NF2004-VA20A
The NF2004-VA20A is a flat thin film thermal printhead that supports medium speed and high speed printing, suited for general purpose compact printers as well as label printers.
!Applications Bar code label printers Ticket printers General purpose compact printers
!Features 1) Standard glazed components to accommodate thick paper. 2) High speed clock to facilitate external heat history control. 3) Using a hard conductive film as a protective film on the heating element offers excellent resistance to electrostatic damage. 4) Compatible with the NF3004-VA20A (300dpi) in mechanical specifications, to facilitate the making of a series of printers.
