The bi-directional transport can move documents in either direction. This feature is used for printing graphics, for rescanning document images, or for ejecting a document at either end of the transport. These printers can print both text and graphics, in either a high or low-speed printing mode. The print area covers almost the entire area of the document, with only small margins at the top and bottom. Like the recognition fonts, the printer fonts are in software.
Programmers can, if necessary, create other fonts.
Thermal Encoding Thermal encoding uses heat to transfer magnetic ink characters onto a document. This advanced technology is quieter than the normal impact encoder technology. The optional NCR 7731 thermal encoder is fully programmable and can encode fonts. One encoding font is supplied with the encoder hardware option, and additional fonts can be purchased. Like all the other fonts, the encoder fonts are in software.
