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
GLOSSARY

used with dot matrix printer fonts. See also ASCII character set; ISO
