ESC/POS Command Manual
29
This command is not effective when the specified NV bit image has not been defined.
In standard mode, this command is effective only when there is no data in the print buffer.
In page mode, the command is not effective.
This command is not affected by print modes (emphasized, double-strike, underline,
character size, white/black reverse printing, or 90
°
rotated characters, etc.),
except upside-down printing mode.
If the printing area width set by GS L and GS W for the NV bit image is
less than one vertical line the following processing is performed only on
the line in question. However, in NV bit image mode, one vertical line
means 1 dot in normal mode (m=0,48) and in double-height mode
(m=2,50), and it means 2 dots in double-width mode (m=1,49) and in
quadruple mode (m=3,51).
The printing area width is extended to the right in NV bit image mode
①
If the printing area width cannot be extended by one line vertically,
②
the left margin is reduced to accommodate one line vertically.
If the downloaded bit-image to be printed exceeds one line, the excess data is not printed.
This command feeds dots (for the height n of the NV bit-image) in normal and
double-width modes, and(for the height
n
x 2 of the NV bit-image) in double-height
and quadruple modes, regardless of the line spacing specified by ESC 2 or ESC 3.
After printing the bit image, this command sets the print position to the beginning of the line
and processes the data that follows as normal data.
