3.5 MAXI CODE Printing
3.5.1 Symbology Parameter
When printing MAXI CODE, set the Symbology parameter to one of the following
values.
PTR_BCS_MAXICODE : Print using MAXI mode 2.
PTR_BCS_OTHER + 0 : Print using MAXI mode 3.
PTR_BCS_OTHER + 1 : Print using MAXI mode 4 or 5. The mode is set to
4 or 5 automatically depending on the length of the
Data parameter. (If the data is long, then the
data correction level is lowered for printing.)
PTR_BCS_OTHER + 2 : Print using MAXI mode 6.
3.5.2 Printing Size
Because the size of MAXI CODE is fixed, printing is done at a fixed size that is
unaffected by the Width and Height parameters. An error occurs only when the
Width and Height parameters fall below zero. If the two-dimensional barcode
cannot fit into the print area (depending on the paper width, layout settings, etc.)
then OPOS_E_ILLEGAL is returned and at this moment ResultCodeExtended
becomes zero.
3.5.3 Printing Position
Like the one-dimensional barcode, the print position of the two dimensional
barcode is the specified position.
3.5.4 Data Format
3.5.4.1 Mode 2
In the case of mode 2, because the format of header + primary message +
secondary message is fixed, data for the Data parameter must follow this format.
The header part contains the following data, which can be omitted.
"[)> RS 01 GS yy" (In hexadecimal: 0x5B 0x29 0x3E 0x1E 0x30 0x31 0x1D 0x..
0x..)
yy is '0' to '9' (0x30 to 0x39)
The primary message part contains the following data.
"Postal Code" GS "ISO Country Code" GS "Service Class Code" GS
Field
Length (byte)
Type
Postal Code
1 to 9
Number (0x30 to 0x39)
ISO Country Code
1 to 3
Number (0x30 to 0x39)
Service Class Code
1 to 3
Number (0x30 to 0x39)
For the secondary message, you can freely specify any data from 0x01 to 0xFF,
and the data can be omitted. Since the length of the encoded data is not known,
the data length cannot be correctly verified. For this reason, if the printer
determines, after examining the original data length, that the data can more or
less be printed, it tries to print the data; if the length is more than that, then an
error occurs. (For the secondary message, an error occurs if the data length is
more than 70 bytes.)

3.5.4.2 Mode 3
In the case of mode 3, except for the format of the primary message, it is same as
mode 2. The primary message of mode 3 has the following type of data.
"Postal Code" GS "ISO Country Code" GS "Service Class Code" GS
Field
Length (byte)
Type
Postal Code
1 to 6
Number (0x30 to 0x39)
A-Z space "#$%&'()*+,-./
ISO Country Code
1 to 3
Number (0x30 to 0x39)
Service Class Code
1 to 3
Number (0x30 to 0x39)
3.5.4.3 Modes 4 and 5
0x01 to 0xFF can be specified to the Data parameter, and there is no restriction
on the format. Since the length of the encoded data is not known, the data length
cannot be correctly verified. For this reason, if the printer determines, after
examining the original data length, that the data can more or less be printed, it
tries to print the data; if the length is more than that, then an error occurs. (An
error occurs if Data is zero byte or more than 80 bytes.)
Mode 4 differs from mode 5 in the error correction level. As much as possible,
OPOS uses the higher error correction level. Therefore, if the data amount is
small (less than 50 bytes), OPOS uses mode 5 (the one with a higher error
correction level).
3.5.4.4 Mode 6
0x01 to 0xFF can be specified to the Data parameter, and there is no restriction
on the format. Since the length of the encoded data is not known, the data length
cannot be correctly verified. For this reason, if the printer determines, after
examining the original data length, that the data can be printed, it tries to print the
data; if the length is more than that, then an error occurs. (An error occurs if Data
is zero byte or more than 80 bytes.)

3.6 QR CODE Printing
3.6.1 QR CODE Printing
When printing QR CODE, set the Symbology parameter to one of the following
values.
PTR_BCS_QRCODE: Print using QR CODE model 2.
PTR_BCS_OTHER + 3: Print using QR CODE model 1 (old specification, used
for maintaining compatibility).
PTR_BCS_OTHER + 4: Print using QR CODE model 2.
3.6.2 Printing Size
Because the width and length of QR CODE are the same, printing is done to the
inner part at a size closest to it by using the value specified by the Width
parameter. Therefore, the height of print is not affected by the Height parameter.
If the Height parameter is less than 0, an error occurs.
The print size is determined by the version of QR and the size of the module.
Because the version of QR is determined by the data length and type, you can
use the size of the module to adjust the print size. If the two-dimensional
barcode cannot fit into the print area (depending on the paper width, layout
settings, etc.) then OPOS_E_ILLEGAL is returned and at this moment
ResultCodeExtended becomes zero.
For QR, it differs from other two-dimensional barcodes; if the encoded data result
is not known, then the print width cannot be obtained. If the print width cannot be
obtained, the page mode range for 90-degree rotated printing cannot be specified.
Therefore, within OPOS it calculates the number of code words of the encoded
data. Because of this reason, data amount can be correctly verified.
3.6.3 Error Correction Level
Error correction level is fixed at 7%.
3.6.4 Printing Position
Like the one-dimensional barcode, the print position of the two dimensional
barcode is the specified position.
