Letter Quality
One of two print qualities available on your printer. Letter Quality
provides better readability and appearance at a reduced print speed.
See also draft mode.
line feed
Both a control code and a panel button that advances the paper one
line space.
loading position
The position to which the paper is automatically loaded. It can be
adjusted by using the micro-adjustment feature.
memory
The printer, like a computer, has a memory. When you print a file from
a computer, the contents of the file are transferred quickly from the
computer’s memory to the printer’s memory. The printer then prints
information from its own memory at a much slower rate. This way of
printing frees the computer to do other work while the printer is still
working. The printer memory is sometimes called the buffer memory or
input buffer.
micro-adjustment
A feature that adjusts the paper loading and short tear-off positions by
the smallest possible increments.
number systems
Three number systems are commonly used with printers:
decimal is base 10 and uses the digits
0, 1, 2, 3, 4, 5, 6, 7, 8,
and 9.
(This is the most familiar system.)
hexadecimal (hex) is base 16 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7,
8, 9, A, B, C, D, E, and F. This is frequently used by programmers.
Any decimal number between 0 and 255 can be expressed by a two-
digit hex number.
