d 1-cell width
When the 1-cell width is 0, a two-dimensional code is not drawn. However, the two-
dimensional code printed on the previous label is cleared.
e Selection of mode
All codes including alphanumerics, symbols, and Kanji can be used in one QR code.
Manual mode or automatic mode can be selected to perform the operation.
f Selection of model
Model 1: Original specification
Model 2: Extended specification which enhances the function of position correction
and can contain a large amount of data.
g Mask number
To be sure the QR code is read, it is preferable that white and black modules are
arranged in this symbol in a balanced manner. This prevents the bit pattern
“1011101”, which is characteristically seen in the position detecting pattern, from
appearing in the symbol as much as possible.
The mask number is 0 to 7. The pattern is determined by placing each masking
pattern for the mask number upon the module pattern. When the mask number is set
to 8, masking is not performed. When the parameter is omitted, the most appropriate
mask number is automatically selected to perform masking.
h Connection setting
For QR code, data can be divided into several codes. Even though there is only a
narrow print space, the code can be entered in the space by dividing the code. The
data can be divided into a max. of 16 codes. Parity data is obtained by XORing all
input data in units of bytes before dividing. The input data is calculated based on
shift JIS for Kanji, or on JIS 8 for others. Examples are shown below:
“0123456789 ” is divided into “0123”, “4567”, and “89 ”.
Code No. 1 No. of divided codes: 3 Parity data: 84 Data “0123”
Code No. 2 No. of divided codes: 3 Parity data: 84 Data “4567”
Code No. 3 No. of divided codes: 3 Parity data: 84 Data “89 ”
* The parity data is the XORed value for “0123456789 ”.
