DV - Define variable text path 

DV [ 

path

 [,

line

]] [;] 

path

 : text printing path - horizontal or vertical, and left to right, right to left, upwards or downwards. 

line

: the effect of a line feed.

 

This command determines the printing direction for labels and the carriage return point. 

 

Permissible values of 

path

 are 0, 1, 2 and 3.    If 

path

 = 0 labels are printed horizontally and left to right - 

normal printing.  If 

path

 = 1 labels are printed vertically downwards - characters appear in a vertical 

column.  If 

path

 = 2 labels are printed horizontally and right to left - words appear backwards.    If 

path

 = 3 

labels are printed vertically upwards - characters appear in a vertical column, reading from bottom to top. 

 

The value of 

line

 must be either 0 or 1.    If 

line

 = 0, each time a line feed is encountered the current pen 

position is moved at an angle of 90º to the path in a clockwise direction.    Hence,    if 

path

 = 1 the second 

line of text is printed to the left of the first line.    If 

line

 = 1 each time a line feed is encountered the current 

pen position is moved at an angle    of 90º to the path in an anticlockwise direction.    Hence,    if 

path

 = 2 the 

second line of text is printed below the first line. 

 

If you do not use a DV command the default text path is horizontal,    left to right: line feeds will move the 
pen position at 90º to the text clockwise.    This is equivalent to using the command DV0,0; 

 

If you omit both parameters the text path is horizontal,    left to right. 

 

CP - Relative character movement 

CP [ spaces [,lines]] [;] 

spaces

 ; the number of text spaces the pen position is moved. 

lines

 ; the number of text lines the pen position is moved. 

 

Use this command to re-position the pen.    The command moves the pen the specified number of lines and 
spaces corresponding to the currently selected font's pitch and line spacing.  (For proportionally spaced 
fonts the width of the space character is used to determine the distance moved horizontally).  All movement 
is relative to the current label printing direction. 

 

spaces

 is the number of spaces that the pen moves.    A positive value of 

spaces

 moves the pen right from the 

current pen location: a negative value moves it to the left. 

 

lines

 is the number of lines that the pen moves.    A negative value offset moves the pen down from the 

current pen location: a positive value moves it upwards. 

 

Values for 

spaces

 and 

lines

 are clamped real numbers. 

 

The command only moves the pen and does not draw lines,    irrespective of whether the pen is currently 
up or down. 

 

On completion of the command,    the previous pen status (up or down) is restored. 

 

The height of text lines (the vertical distance that a line feed moves the pen position) is fixed for every 
font.    However,    it can be adjusted using the ES instruction. 

 

If you omit all parameters, the pen position moves to the carriage return point and then down one line - 
hence CP; is equivalent to a carriage return followed by a line feed.

  • 3. If path = 0 labels are printed horizontally and left to right - normal printing.
  • 1. If line = 0, each time a line feed is encountered the current pen position is moved at an angle of 90º to the path in a clockwise direction.
