EFP9800 ESC/POS Commands

Set Relative Print Position

Sets the print starting position based on the current position, in the fundamental calculation pitch. The distance (in inches) from the current position is calculated as: [N x (fundamental calculation pitch)]. See the Set Fundamental Calculation Pitch command (1D 50).

Pitch N to the right is calculated as: (n1 + n2 x 256). Pitch N to the left is calculated as:

(n1 + n2 x 256) = 65535 - N.

The print position moves right when the result is a positive number, and left when the result is a negative number.

Hexadecimal	Decimal	ASCII	Value of n1	Value of n2
1B 5C n1 n2	27 92 n1 n2	ESC \ n1 n2	0 -255	0 -255

Standard Mode

The horizontal direction of the fundamental calculation pitch is used to calculate the print starting position.

Page Mode

Two types of fundamental calculation pitch are used to calculate the print starting position, depending on the value of the Select Print Direction in Page Mode command (1B 54 n). For more information see “ Page Mode” later in this section.

•If 1B 54 n = 0 or 2, the horizontal direction of the fundamental calculation pitch is used.

•If 1B 54 n = 1 or 3, the vertical direction of the fundamental calculation pitch is used.

The command is ignored when the start position specified is beyond the beginning or end of the line or outside the printing area width or the left margin.

Select Justification

Begins justification as specified by the value of n. Any blank space (for example as a result of setting the relative or absolute print position or a tab) is also justified.
