• When you use an LO instruction the carriage return point is set to be the new label origin.
back to a label's origin when you have finished printing it, include a carriage return between the last
character of the label and the terminating character.
• If a label contains embedded carriage returns, each character string following a carriage return is printed
starting from the label origin.
• If you omit the parameter the label origin is the bottom left hand corner of the first character's character cell -
equivalent to LO11;.
• The command remains in effect until the printer is initialized with an IN command,
conditions are restored with the DF command or until another LO command is used.

DI - Absolute direction
DI [ run, rise ] [;]
run : X direction component rise : Y direction component
• This command determines the direction in which subsequent labels will be printed.
rise
•
gives the tangent of the angle between the base line of a label's characters and the horizontal.
run
• run is equivalent to cos θ and rise is equivalent to sin θ.
• Values for run and rise are clamped real numbers.
• When you issue a DI instruction the carriage return point is set to the current pen location.
• The instruction is ignored if run and rise are both 0.
• Any text path that you set with the DV instruction will combine with the current printing direction to
determine the layout of characters on the page.
• If you omit the parameters the printing direction is horizontal.
• The label direction which is specified by this command is not affected by changes in the location of P1 and
P2.
