Printronix ThermaLine Series manual Defines the ending column of the box. Enter a value

NOTE: If the SCALE;DOT command is used to specify the dot resolution, the line thickness will be specified in that dot scale, rather than as the standard 1/72º line.

EC	Defines the ending column of the box. Enter a value
	ranging from column 2 through the last column of the
	form. The ending column must be greater than the
	starting column. Character column or dot column is
	specified based on the Scale command (page 4±88), or
	use the CP.DP format (page 4±7).
STOP	Stop indicates the end of the Box command; enter
	STOP, and the IGP/PGL will wait for a new command.
	If not entered, the IGP/PGL will wait for another set of
	Box command parameters.

Example The following program and example in Figure 4±4 defines two boxes. To illustrate positioning, the starting row and column are indicated on the example but do not necessarily reflect actual location on the page. (Note the position of the ending row and ending column; they do not include the line thickness.)

BOX
3;24;16;51;63	(One box three dot rows thick)
2;44;48;46;58	(One box two dot rows thick)
