ESC ＠
Decimal: 27 64

This command is used for initializing the printer, and its function is described as follows:
(1) Clearing the data in the print buffer and line-editing buffer.
(2) Resuming the default value.
(3) Setting the printing mode of Chinese character.
(4) Deleting user-defined characters.
ESC C Set the page length according to line spacing
Format: ASCII: ESC C n
Decimal: 27 67 n
Hex: 1B 43 n

The command sets the length of detecting black mark in the meantime. If the black mark can’t be detected
in this length, then it is considered that the paper has no black mark.
The specified page length = current line spacing* n.
ESC D Set horizontal tab positions
Format: ASCII: ESC D n[k] NULL
Decimal: 27 68 n[k] 0
Hex: 1B 44 n[k] 00
[Description]
Set horizontal tab positions to n1, n2, …, nK.
For BP-007, k＝1~21, and it can set 21 horizontal tab positions at most.
The absolute horizontal position of the first horizontal tab is: n1 times of half-dot distance;
The absolute horizontal position of the second horizontal tab is: (n1+n2) times of half-dot distance;
The absolute horizontal position of the third horizontal tab is: (n1+n2+n3) times of half-dot distance;
……
The absolute horizontal position of the Kth horizontal tab is: (n1+n2+n3+……+nK) times of half-dot
distance;
Default value: n1=n2=……=nK=10.
All the horizontal tab positions (ni) should be within the line width allowed by the printer. ni=1~80, it is equal
to 40 7×7 or 7×9 dot matrix characters width, or equal to 20 16×15 Chinese characters width.
After executing “ESC D” command, changing the kind and size of characters will not affect tab positions
already set. This can guarantee that tab is put in order when Chinese characters are confused with
common characters in one line, or when characters are magnified or shrinked.
NUL put in the end means that this command is over.

1st printing.
• When n is 0, boldface printing is invalid.
