ECP

Extended Capability Port. ECP is a protocol that provides for a high performance bi-directional communication path between the host adapter and the peripheral. To take advantage of ECP mode, the parallel port must be capable of operating in ECP mode, there must be a port driver that knows how to operate in ECP mode, and the printer or peripheral must be designed to operate in ECP mode.

EPP

Enhanced Parallel Port. EPP is a protocol that provides for a high performance parallel port link that is still compatible with the standard parallel port. Details of this standard protocol are available from the IEEE 1284 committee.

Error Diffusion

Highest quality of all halftoning methods. Optimal for printing photographic and graphic images.

Font

A complete set of characters of the same size and style; a particular implementation of a typeface. For example, 12-point, Courier bold.

Form feed

A printer function that automatically ejects the current page and advances the printer to the top of the next page.

Gamma

Degree of intensity for a printed color image from the monitor screen display. The default Gamma Setting for the BJC-5100 is 1.4. The lower the number, the brighter the printout image.

Grayscale

Representing color in black and white as a result of different intensities of color. Different colors and intensities of colors appear as different shades of gray.

Halftoning Method

Technique of creating various colors and shades by using different sizes of dots and spaces.
