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 (if present)
The following igure shows an example of tickets with “Black Mark Distance” set to 0:

A “Non-printable area” generated from:
“Distance between cutter/printing head” - “Value for the paper recovery after a cut”
where:
“Distance between autocutter/printing head” = 11.9 mm (ixed distance)
“Value for the paper recovery after a cut” in VKP80II emulation= 0 mm,
“Value for the paper recovery after a cut” in VKP80III emulation = variable from 0 mm (default value) to 11.9 mm
according to the settings of 0x1C 0xC1 command (see commands manual)
H Distance between the irst and the last print 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 the 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.
