Glossary G-7
parity
A method for detecting errors during data transmission through a serial interface.
pitch
The font attribute that determines the placement of printed characters. Two types of pitch
are available: fixed pitch (characters are printed at equal intervals) or proportional pitch
(character placement varies, depending on character width information).
point size
A measure of character height. One point equals 1/72 inch. In ESC/P 2, point size can be
set as a font attribute.
print data
Data that causes the printer to actually print characters or graphics. Data that sets the page
format, selects printing modes, or changes printer settings is not considered print data.
print job
A collection of data that has a beginning and end, and is sent to the printer in a continuous
stream. A standard print job should be composed of one or more pages and should begin
and end with an ESC @ (initialize printer) command, with all pages (including the last)
ending in a FF command.
printable area
The area of the page on which the printer can print. This area is smaller than the physical
size of the page.
printing area
The area of the page within the margins, where printing actually occurs. The printing area
is equal to or less than the printable area.
proportional spacing
A type of pitch in which character placement varies, depending on character width
information.
pull tractor
A tractor that “pulls” continuous paper through the printer from the exit side.
push tractor
A tractor that “pushes” continuous paper through the printer from the loading side.
RAM
Random access memory. The portion of the printer’s memory used as a buffer and for
storage of user-defined characters. RAM memory is lost when you turn off, reset, or
initialize the printer.
raster graphics
A type of graphics in which data is sent in one-dot high lines; the printer reorganizes the
data internally to correspond to the print head layout. Raster graphics are available only on
printers featuring ESC/P 2.
ROM
Read only memory. The portion of the printer’s memory where the printer’s operating
system and built-in character data are stored. You cannot erase or modify ROM memory.
