7.4 Printing area
In order to print ticket containing only one black mark and to not overlay printing to a black mark (that will make it useless
for the next alignment), it is important to well calibrate:
•
the length of the printing area of ticket according to the inter-black mark distance;
• the value for the paper recovery after a cut.
The following igure shows an example of tickets with “Black mak Distance” parameter set to 0:

PRINTING DIRECTION
A “Non-printable area” generated from:
“Distance between cutter/print head”- “Value for the paper recovery after a cut”
where:
”Distance between cutter/print head” = 24 mm (ixed distance)
“Value for the paper recovery after a cut”= 9 mm (in CUSTOM/POS emulation)
24 mm (in SVELTA emulation)
In CUSTOM/POS emulation, after a performed cut, the paper is not completely recovered (in order to avoid jam-
ming when using of thin paper). Otherwise, in this emulation you can use the command 0x1C 0xC1 to modify the
“Value for the paper recovery after a cut” (refer to the commands manual of the device).
The SVELTA emulation, instead, it is designed speciically for ticketing and then for using with heavy paper, which
avoids the risk of paper jams. After performing a cut, the device completely recovers the paper
H Distance between the irst and the last printing line, called “Height of the printing area”.
L Distance between an edge of the black mark and the next one, called “Inter-black mark distance”.
D Automatic feed for alignment at the next black mark.
To use all the black marks on paper, you must comply with the following equation:
H + A ≤ L
The height of the printing area (H) can be increased to make no progress on alignment (D) but no further.
