media;(Used instead of medium.) The material on which the graphics are plotted: paper, translucent material, vellum, film, or special paper.

media axis;The axis along which the me< dia moves. (X<axis; paper axis.)

media jam;￿ situation in which media becomes blocked in the plotter mechanisms.

media*jam lever;Pinch<arm lever.

media*length calibration;Media<sensor calibration.

media*sensor calibration;Media<length calibration.

mil;1/1000 of an inch.

minimum pass time;The time necessary for ink to dry sufficiently before the plotter can place more ink adjacent to it.

MIO;Modular Input/Output.

mm;Millimeter(s).

monitor mode;Service monitor.

MS*DOS;MicroSoft ￿isk<Operating Sys< tem

no negative motion;￿n RTL command that indicates to the plotter that it will re< ceive all data already in the order in which it should be plotted.

off*axis ink system;￿ system whereby ink is pumped to the cartridges from a res< ervoir that does not move with the carriage.

PAL;Programmable ￿rray Logic.

palette; ￿ set of pens for which width and

paper axis)Media axis (X<axis).

parity;￿n error<checking method for in< formation transfer between a computer and a peripheral device. Parity is used to check the accuracy of binary data.

pass;￿ movement of the carriage from left to right, or from right to left, as it plots the graphic.

pass advance;The distance that the me< dia advances between carriage passes.

PC;Personal ￿omputer.

PCA;Printed ￿ircuit ￿ssembly.

pen;1. Even though the inkjet plotter has no physical pens, the lines it draws match the attributes for pens numbered 1 through 8 in the application software. (See also •palette.")

2.Sometimes used instead of •print car< tridge."

pinch*arm lever;Pinch<wheel lever, me< dia<jam lever.

PJL)Printer ￿ob Language, developed by Hewlett<Packard to give software applica< tions more job<level device control and to provide device status information to the ap< plication.
