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 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.)
3.6 QR CODE Printing
3.6.1 QR CODE Printing
When printing QR CODE, set the Symbology parameter to one of the following
value
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.
PTR_BCS_UQRCODE : Print using Micro QR CODE.
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.
