Hexadecimal.
A numbering system based upon 16 rather than 10. The letters A-F substitute for the decimal values 10-15.
Hexadecimal is commonly used in computer programming because each digit represents exactly half a byte. This
makes translation to and from binary easy and the notation takes less space than the equivalent decimal notation.
Horizontal Tabs.
Horizontal tabs are the ordinary typewriter-style tab stops that can be set on your printer by using a tab-setting
command. When the tabs are set, a tab command (ASCII character 9) moves the printhead to the next tab stop.
I-Prime.
A signal sent by some computers which clears all temporary memory areas of the printer and resets all default
modes.
IBM character sets.
IBM Character Sets I and II are variations of standard ASCII and the IBM PC character set. IBM Character Set I
is distinguished by providing control codes in the regions between characters 3 and 6, and between 128 and 159
(decimal). IBM Character Set II contains symbols in these locations. Otherwise, the two sets are the same.
Interface.
The connection between two pieces of equipment_that is, between a computer and a printer. The two basic types
of interfaces are parallel and serial. The word is loosely used to mean either the method of connection or the
actual hardware used to connect equipment. As a verb, it usually means the act of making the connection.
Italics.
Slanted printing created by using a separate character set or by altering a normal character set while printing.
LED.
Light Emitting Diode: Small colored lights used by the printer to indicate printing status and error conditions.
Letter Quality.
A dot matrix print quality comparable to that produced by a typewriter.
Line Feed.
A line feed command (ASCII character 10, decimal) simply drops the printhead to the next printing line.
Generally, it also automatically returns the printhead to the first position.
Line spacing.
Line spacing is generally specified in lines per inch (lpi). A common value is 6 lpi; a more condensed page may
use 8 lpi.
Lines per inch.
A measure of line spacing. When the line spacing is 6 LPI, the distance between the bottom of one line of print
and the bottom of the next is 1/6-inch.
LPI.
See Lines per inch.
LPRINT.
The print statement in the BASIC computer language.
LPT.
Abbreviation for lineprinter, this is used as the printer name in PC-DOS. The first printer connector is called
LPT1:, the second is called LPT2:.
LQ.
See Letter Quality.
