(19) Explanation for CP code

ECC (Error Correction Code) level
The CP code contains a function to correct a code reading error using an error
correcting code word and restore normal data. The error correction level is selected
according to usage to perform the error correction function.
The higher the percentage of the error correcting code word is, the higher the error
correcting ability is.
For the CP code, the program is designed so that all remaining areas are used for
correcting errors when the number of code characters is specified by a user. When
the number of code characters is specified, "0" (No designation) can be used.
When the number of code characters is not specified by the user, a value from 10 to
50% must be selected. The printer automatically determines the number of code
characters so that the error correcting code word exceeds the percentage specified by
the user.

The number of bits per character
Data is compressed by using the 8-bit compaction method. If "0" is specified, the data
is compressed in the same way.
Character set for 8 bits
8 bits: ISO

The number of code characters
For the CP code, a 3×3 cell is used for one block, and the block set forms the CP
code.
The numbers of characters in X and Y directions can be set by the user.
When "0" is specified, the printer automatically sets the smallest code size in which
data set by the user can be contained.
The rectangular code can be specified. The value for the Y direction must be smaller
than the X direction.
The number of cells for the code is as follows.
(No. of code characters) × 3 + 2
00H to FFH (for Kanji)
