Resolution.
The number of dots per inch (dpi) in a graphics pattern.
Ribbon cartridge.
The cartridge containing the printer ribbon. You should always make sure that the cartridge is correct for the
printer and is properly seated. Your ML380 printing ribbon cleans and lubricates the head while printing, so using
the wrong ribbon could actually damage your printhead. For the best results, be sure to use genuine OKIDATA
ribbons.
Rolling ASCII self test.
A printer test in which all of the ASCII characters are printed continuously until the test is stopped or the printer
is turned off.
ROM.
Read-Only-Memory: A permanent storage device (integrated circuit chip). Information stored in ROM_called
firmware_can be read but cannot be added to or changed. In most printers, ROM is used to store the dot patterns
that make up the character sets, instructions for interpreting control codes, etc.
RS-232C.
A standard for serial interfaces set by the Electronic Industries Association (EIA).
Sans-serif.
A typeface in which the letters are plain and do not have any hairline extensions (serifs) at the tips.
Self test.
A method of testing the printer prior to connecting it to a computer. Several self test routines are available with
each printer.
Serial.
A serial connection or interface is one in which data is sent one bit at a time. This type of connection is generally
used in data communications and on networks. It is slower than a parallel connection, but can be carried over a
longer distance.
Serif.
A typeface in which the letters have decorative hairline extensions at the tips. Serif typefaces are frequently used
for text in books and newspapers.
Sidebar.
A short section of text accompanying the main body of text and providing a more detailed explanation or
presentation of a particular point or item mentioned in the main text. Sidebars are generally set in smaller size
type than the main body text.
Skip Over Perforation.
This feature, when activated, insures that the printer does not print across the perforation on continuous forms by
providing an automatic 1-inch bottom margin.
Slashed zero.
The slashed zero is a zero character with a line through it to distinguish it from the character O. This feature is
useful in certain applications but is inappropriate for others, so your printer offers a choice between the plain zero
and the slashed zero.
Software.
A program or set of instructions that tells your computer or printer what to do. Its called soft because, like words,
it doesnt really have a physical form the way something like a rock does. A software package is a commercially
prepared program or set of programs, usually sold recorded on a disk.
