Chapter 7 Print Control Codes
(21)Printer initialization (ESC @)
Code: [1B] h + [40] h
Clears data stored in the internal print buffer and sets each setting in its initial state (default state).
•Data in the internal input buffer are not cleared.
•Macro definition contents are not cleared.
(22)Setting the horizontal tab position (ESC D n NUL)
Code: [1B] h + [44] h + n + [00] h
*(1 ≤ n ≤ FF) Data are expressed in Hex code.
This command sets the horizontal tab position.
•n indicates the number of lines from the left margin to the horizontal tab position.
•The tab position is set at the character width x n position from the top of the line. At this time, the character width includes the space to the right of the character and when the horizontal enlargement rate is 2 or greater, the character width is also made larger corresponding to the enlargement rate.
•The maximum number of places a tab position can be set is 32 positions. Settings exceeding this number are disregarded.
•ESC D NUL clears all the set tab positions. After clearing, the horizontal tab (HT) is disregarded.
•The initial value is every 8 characters for Font A and the amount of right space at 0 (9th column, 17th column...).
(23)Specifying/Clearing bold characters (ESC E n)
Code: [1B] h + [45] h + n
*(0 ≤ n ≤ FF) Data are expressed in Hex code. This command specifies and clears bold characters.
•The least significant bit (n0) in n is valid.
•Control by the least significant bit (n0) is as follows.
n0 = 0: Clears bold printing.
n0 = 1: Specifies bold printing.
•This is valid for all characters.
•The dot configuration of bold characters is one dot each added to each character horizontally.
