Set Relative Print Position
ASCII: ESC \ n1 n2
Hexadecimal: 1B 5C n1 n2
Decimal: 27 92 n1 n2
Value of n :
To Move the Relative Starting Position Right of the Current Position by
n dots:
n 1 = Remainder after dividing n by 256.
n 2 = Integer after dividing n by 256.
The values for n 1 and n 2 are two bytes in low byte, high byte word orientation.
To Move the Relative Starting Position Left of the Current Position by n dots:
n 1 = Remainder after dividing (65,536- n ) by 256
n 2 = Integer after dividing (65,536- n ) by 256
The values for n 1 and n 2 are two bytes in low byte, high byte word orientation.
Moves the print starting position the specified number of dots either right (up to the right
margin) or left (up to the left margin) of the current position. The print starting position is
reset to the first column after each line.
Formulas:
To move to the left:
Determine the value of
n by multiplying the number of columns to move left of the current
position by 13 (receipt standard pitch) or 10 (slip or receipt compressed pitch). The
example shows how to set the relative position two columns in standard pitch (10 dots per
column) to the left of the current position.
2 x 10 = 20 dots (two columns to be moved left of the current position)
65,536-20 = 65516
65,516/256 = 255, remainder of 236
n1 = 236 n2 = 255
To move to the right:
Determine the value of
n by multiplying the number of columns to move right of the
current position by 10 (slip or receipt standard pitch) or 8 (receipt compressed pitch). The
example shows how to set the relative position two columns in standard pitch (10 dots per
column) to the right of the current position.
2 x 10 = 20 dots (two columns to be moved right of the current position)
20/256 = 0, remainder of 20
n1 = 20 n 2 = 0
Example:
MSComm1.Output = Chr$(&H1B) & Chr$(&H5C) & Chr$(n1) & Chr$(n2)
