Ruled line pattern set (
DC3 F
)
Code:
[13h] + [46h] + n1 + n2
The command fills the selected ruled line buffer with the data sequence
n1
,
n2
. Permitted
values: 0-FFh. Every byte sets 8 dots, last executed command
DC2 =
determines whether the MSB is
the left or the right side.
The existing data in the buffer are replaced with the new data.
Dots outside the printable area are ignored.
The command is supported in firmware version 1.48 or higher.
15.
Ruled line line set (
DC3 L
)
Code:
[13h] + [4Ch] + mL + mH + nL + nH
The command sets to ‘
1
’ the bits between to specified coordinates in the selected ruled line buffer.
The coordinates are
mL+256*mH
and
nL+256*nH
. The part of the line outside the printable area is
ignored.
The command is supported in firmware version 1.48 or higher.
16.
Selects ruled line combine mode (
DC3 M
)
Code:
[13h] + [4Dh] + n
The command selects the logical operation between the selected ruled line buffer and the print buffer
when ruled line is enabled.
n
is from 1 to FFh, but only the LSB is used:
0
: OR operation – bit ‘1’ in ruled line buffer sets a black dot on paper.
1
: XOR operation – bit ‘1’ in ruled line buffer inverts the dot.
For commands
DC3 P
,
DC3 p
and when printing an empty line the logical operation doesn’t matter.
Logical operation XOR is useful to invert the whole height of a text line (white letters on black
background).
By default OR mode is selected (value
0
).
The command is supported in firmware version 1.48 or higher
.
17.
Ruled line one dot line print (
DC3 P
)
Code:
[13h] + [50h]
The active ruled line buffer is printed as a single line (0.125 mm high).
If ruled line is off, then the paper is moved one line (0.125 mm) without printing.
If there are graphic or text data in the line, they are ignored (erased).
The same effect will have command
ESC 3 [01h]
without text or graphic data in the line.
good.
The command is supported in firmware version 1.48 or higher.
18.
Ruled line
n
dot line print (
DC3 p
)
Code:
[13h] + [70h] + nL + nH
The selected ruled line buffer is repeated on
nL+256*nH
lines.
If ruled line is off, then the paper is moved
nL+256*nH
dots without printing.
If there are graphic or text data in the line, they are ignored (erased).
The same effect will have command
ESC 3 n
without text or graphic data in the line (the difference is,
that the possible line height is up to 255 dots).
Warning!
Because of the characteristics of thermal printing it is possible, that the quality of single horizontal lines on the
paper is not
