(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.
