micro feed
A feature that you use to adjust the paper loading and tear-off
positions, and a control panel button you use to feed paper, either
forward or backward, in 1/180-inch increments.
parallel interface
See interface.
platen
The black roller that provides a backing for the paper during
printing.
printable area
The area of a page on which the printer can print. It is smaller than
the physical size of the page due to margins.
proportional printing
Printing in which the width of the character varies from character
to character. For example, a capital W receives much more space
than a lowercase i. The result looks more like a typeset book than a
typewritten draft.
RAM
Random access memory. The portion of the printer’s memory used
as a buffer and for storing user-defined characters. All
data stored in RAM is lost when the printer is turned off.
reset
To return a printer to its default status by sending a command or
an INIT signal or by turning the printer off and then back on.
self test
A method for checking the operation of the printer. When you run
the self test, the printer prints its current DIP-switch settings and
the characters stored in its ROM.
standby position
The position in which the paper is attached to the push tractor but
not in the paper path.
