DR - Relative direction
DR [ run, rise ] [;]
run : X-component of the printing direction expressed as a percentage of the x-component of the
distance between P1 and P2.
rise : Y-component of the printing direction expressed as a percentage of the y-component of the
distance between P1 and P2.
• This command determines the direction in which subsequent labels will be printed.
• Values for run and rise are clamped real numbers.
• The instruction is ignored if run and rise are both 0.
• When you issue a DR instruction the carriage return point is set to the current pen location.
• 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 change the positions of P1 and P2 the printing direction will change accordingly.
• If you omit the parameters the printing direction is horizontal and the run = 1% of |P2X-P1X|.
• Actual values for run and rise are changed relative to the P1 and P2 value.
actual run = run parameter ÷ 100 x (P2x - P1x)
actual rise = rise parameter ÷ 100 x (P2y - P1y)
