PE, Polyline Encoded

This command incorporates the PA, PR, PU, PD, and SP commands

into an encrypted format that substantially decreases the size of your

file and the time required for data transmission. (This command is

especially useful when using an RS-232-C interface.)

PE [flag[value]]|coord_pair...[flag[value]]|coord_pair;

PE;

Note Parameter values are self-terminating; do not use commas with this

command. Also, you must use a semicolon to terminate PE.

Lines are drawn using the current line type and current units. The

printer draws to all points with the pen down unless a pen up flag

precedes the X,Y coordinates. If the final move is made with the pen

up, the pen remains in the up position; otherwise the pen is left in the

down position.

The PE command causes the printer to interpret coordinate pairs as

relative coordinates unless they are preceded by an absolute value

flag (=). Relative integer coordinates produce the most compact data

stream. For best results, scale your drawings so you use only integer

coordinates and use relative plotting mode. After PE is executed, the

previous plotting mode (absolute or relative) is restored.
