Chapter 2 Command Codes

Explicit Positioning Commands

The horizontal print position can be changed using the Horizontal Tab

command. With the Horizontal Tab command, any horizontal print position on

the current print line can be specified as the print position.

NOTE: The control panel form feed key will operate differently dependent on

the source of form feed control at the time the key is pressed. Form

feed is controlled by the LP+ and Code V emulation at different times.

The vertical print position can be changed using the Justification command or

justification parameter within one of the alphanumeric commands. The

Justification command or parameter specifies a vertical position down the

form from the current print position. Additionally, you can use standard

graphics commands for line slew, dot slew, line feed, form feed, or EVFU

commands to specify a vertical print position.

These positioning commands and their use are described within this chapter.

It is important to remember that the end of a command sequence always

resets the starting position for all subsequent positioning to row 1, column 1 or

the left Graphics margin.

Vertical Dot Density

A vertical tenth-inch equals 7 dots based on 72 dpi vertical dot density. A true

vertical tenth-inch at 72 dpi would be 7.2 dots. Since .2 dots is not printable,

seven dots are used and the vertical measurement of a line, box, or similar

graphic element is not exact.

You can enable the “True Vert 1/10” option which allows the vertical size/

position parameter to be in true inches. With this option enabled, vertical

dimensions will be as close to true as possible based on a 72 dpi density

(e.g., 1.0 inch is exact at 72 dots. While 1.2 inch is close at 86 dots, exact

would be 86.4 dots.)

Command Codes

The tables on the following pages list each Code V command according to the

Graphics Mode in which it operates. Following these tables, each command in

this chapter is presented in alphabetical order.
