DT - Define label terminator
DT [ c [, m ]] [;]
c : Character
m : mode
• This command allows you to specify the character that terminates strings printed with the LB instruction.
•
The character immediately following DT is taken to be the terminator. Hence, do not put a space
between the DT and your chosen character. If you do, space will be interpreted as the terminator in all
subsequent LB commands.
• m, the mode, determines whether the terminating character is printed as part of the label or not. If m = 0
the character is printed ; if m = 1 it is not.
• If you do not specify a value for m the terminating character is not printed.
• If you leave out the character parameter the default character ETX (ASCII 3 ) is used as the terminator.
•
This setting is effective until the another DT is invoked or IN or DF is performed.

LO - Label origin
LO [ p ] [;]
• This instruction allows you to position labels in different ways relative to the current pen location.
• You can centre, left justify or right justify labels relative to the current pen location and print them on,
above or below the current location.
• You can combine an offset distance, equal to 25% of the current font's point size, with any of the above
origin positions.
• p must either be in the range 1 - 9, 11 - 10 and 21. The label origin position specified by each p parameter
value is shown below. 21 sets the label origin to the same one in PCL.
P=1 P=4
P=2 P=5
P=3 P=6
P=11 P=14
P=12 P=15
P=13 P=16
