CCH top-level constant
String
const CCH
Cancel Character.
CCH is used to indicate that both the preceding graphic character in the data stream, (represented by one or more bytes) including SPACE, and the control function CCH itself are to be ignored for further interpretation of the data stream.
If the character preceding CCH in the data stream is a control function (represented by one or more bytes), the effect of CCH is not defined by Standard.
Implementation
const String CCH = '${ESC}T';
