A.1.2 Alignment Description
The $1D $F6 command searches for the reference notch on the paper and move the label with the value of nH e
nL parameters. For move in the exact point for printing on the label just give the right values to parameters nH
and nL.
Example: To print a logo on a ticket like in to fig.A1 with the hole (or notch) at the end of the ticket,
the following command must be sent:
$1D, $F6, $FF, $7B (perform alignment)
$1B, $FA, $00, $55 (print logo)
In this example, nH and nL are expressed in module 2 so that the motor will recede.
The nH e nL parameter are calculated in the following mode:
1) Find the shift to effect, after the alignment from:
Distance =Label dimension - Distance from sensor end printing line=
= 25.4 (mm) - 8.7 (mm) = 16.7 mm
2) Distance in dot ( express at 200 dpi ) = 16.7 (mm) * 8 (dot/mm) = 133 dot
3) The shift is negative because the motor must be moved backwards and
then should be express number in complement 2 whose corresponds to $FF $7B.
NOTE: Among printers could be a difference among alignment, these difference is dued from the
sensibility of the alignment notch.
