•Even if the printer is not selected, the printer may, according to its operation, enter the BUSY state.
•The initial value is “n = 1”.
(20)Erasing download characters (ESC ? n)
Code: [1B] h + [3F] h + n
* (20 ≤ n ≤ 7E) Data are expressed in Hex code.
The download characters with the specified code are erased.
•n indicates the character code that erases the definition pattern. After erasure, printing of the same patter as internal characters is done.
• The specified code definition patters of character fonts selected by ESC ! are erased. | 7 |
