5.6 Hole / Black mark detection commands
GS L n
Description: Set Mark length
Format:
<1Dh> <4Ch> <n>
Comments: Set Mark length and switch from continuous paper feed to mark detection.
n specifies the length of the mark in dot lines at 0.125mm. If n = 0 (Default) then the
printer switches into continuous paper feed mode.
Example : If n = 24 the length of the mark is equal to 3mm, and the printer enters the mark
detection mode.
The minimum mark length is 2.5 mm and the maximum is 7 mm.
Note : sending this command clears the hole/mark detection error bit in the printer status.
GS T n1 n2
Description: Sets top of form (TOF) position
Format:
<1Dh> <54h> <n>
Comments: Defines the number of dot lines N between the end of the mark and the first printable
line (TOF).
N = (256*n1) + n2. By default, N = 0 dot lines.
GS E
Description: TOF feed paper
Format: <1Dh>
<45h>
Comments: Makes paper feed to the next TOF position. The hole/mark detection error bit in the printer
status is automatically cleared when the black mark is found.
