A.1 TICKET ALIGNMENT
A.1.1 Ticket alignment
Paper stock with alignment marks is permitted so that tickets of a fixed length or with
pre-printed areas may be utilized.To guarantee proper alignment, the "Alignment" pa-
rameter must be enabled under setup using the key (see: setting configuration para-
meters) The notch mark must be placed on the termic side of the ticket itself
(printable area) .
The label dimension is:
* The listed value showed with on asterisk in the fig.A1 indicates the minum dimensi-
on controlled
A.1.2 Alignment Description
The GS F6 command searches for the reference notch on the paper and muve the la-
bel with the value of nH e nL parameters o 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:
0x1D, 0xF6, 0xFF, 0x7B (perform alignment)
0x1B, 0xFA, 0x00, 0x55 (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.
