11.4 Printing area
In order to print ticket containing only one notch and to not overlay printing to a notch (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-notch distance;
• the value for the paper recovery after a manual tear-off.
The following igure shows an example of tickets with “Notch Distance” set to 0:

A “Non-printable area” generated from:
“ Distance between tear-off line/printing head”- “Value for the paper recovery after a manual tear-off
”
where:
”Distance between tear-off line/printing head” = 24 mm (ixed distance)
“Value for the paper recovery after a manual tear-off”= 9 mm (in CUSTOM/POS emulation)
24 mm (in SVELTA emulation)
In CUSTOM/POS emulation, after a performed tear-off, the paper is not completely recovered (in order to avoid
jamming 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 manual tear-off” (see commands manual).
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 tear-off, the device completely recovers the paper
H Distance between the irst and the last print line, called “Hieght of the printing area”.
L Distance between an edge of the notch and the next one, called “Inter-notch distance”.
D Automatic feed for alignment at the next notch.
To use all the notches 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.
