Glossary
Resolution
The fineness of the printing. Resolution depends on the number of
dots per inch. High resolution (with more dots) is finer and more
precise than low resolution, which is coarser with rougher edges.
Scalable font
A font capable of printing in any point size. Scalable fonts are stored
on the computer’s hard disk. Each font consists of character
templates that are used by the accompanying font utility software to
create the characters in the desired point size.
Some font utilities create a complete set of characters in the desired
size and send the complete set to the printer. Other utilities create
and send only the individual characters as they are needed, which
conserves printer memory.
Serial interface
A connection between the computer and printer in which data is
transmitted sequentially over a single wire. A serial interface is slower
than a parallel interface, but it can send data over a much greater
distance. The RS-232C interface is a type of serial interface. See also
Parallel interface.
Serial protocol
A set of rules used by the computer and the printer to regulate the
flow of data between them.
Symbol set
The set of characters used in a font. Most symbol sets contain
standard letters, numbers, and punctuation. Symbol sets differ in the
accented characters, line drawing characters, and special symbols they
contain. ASCII, Roman-8 and PC-8 and examples of symbol sets.
Symbol sets are also called character sets, which is the term usually
used with dot matrix printer fonts. See also ASCII character set; ISO
symbol set.
