Epson DFX-8500 Operation Manual

Glossary

application program (software)

A program designed to perform a specific function. Examples are word processing, spreadsheet, and database programs.

ASCII

The American Standard Code for Information Interchange. ASCII codes are assigned to particular characters and control codes used in operating computers and printers. The

ASCII code table is included in the Appendix.

attribute byte(s)

Parameters used when defining user-defined characters. Depending on the type of printer, the attribute byte can determine the width of a character, beginning and ending columns, and which pins to use in the print head.

automatic tear off

A printer feature that feeds the last page of a print job on continuous paper to a position where paper can be conveniently torn off. When more print data is sent, the paper feeds back to the loading position and begins printing on the following page. This feature is only available when using a push tractor.

bar code

A group of vertical bars and spaces with varying widths that represent numbers and letters.

Bar codes are usually used to identify items such as commercial goods, products, and books.

baseline

The imaginary line where the bottom of characters such as A and b are printed (descenders on characters such as g or y descend below the baseline). The baseline on 24-pin printers is located 20/180 inch below the print position; on 9-pin printers, 7/72 inch below the print position.

baud rate

The rate at which data is transferred from one machine to another. The baud rate is adjustable when using a serial interface. Some printers allow adjustment by DIP switch.

compression

A method of reducing the amount graphics data sent to the printer during raster graphics printing. In standard compressed raster graphics, two bytes of data (a counter byte and a data byte) can specify up to 1,016 dots. Also, repetitive and nonrepetitive data can be sent in the same data string. See also TIFF compressed mode.

default

The value or setting that is in effect when a printer is turned on, reset, or initialized.

Defaults are sometimes affected by DIP-switch or panel setting.

DIP switch

Stands for dual in-line package switch. Small switches included on most printers used for selecting various features or default settings.

dot matrix

A method of printing in which each character is formed by printing a pattern (matrix) of dots based on the number of dots in the print head.

dots per inch (dpi)

Measures the resolution of an image. See also resolution.

Glossary G-3

The part of the printer where character information and data are stored.

MicroWeave

Printing in which images are printed in finer increments to reduce the possibility of banding—uniform horizontal lines in graphics—usually associated with serial printers.

MOD

The remainder of a division operation (modulo). For example, dividing 9 by 5 results in 1, with a remainder of 4; so MOD(9÷5) is 4.

top-of-form

The first printable vertical position on the paper. Programs should be written so the actual top-of-form position matches the printer’s top-of-form setting.

typeface

Refers to a set of characters or symbols that share a common design. Typefaces are referred to by family names such as Roman, Prestige, or Script. In computer terminology, the term typeface is often used interchangeably with font.

unidirectional printing

Printing in one direction only. Unidirectional printing is useful for printing graphics because it allows more precise vertical alignment than bidirectional printing.
