[Description] Encodes and prints the QR Code symbol data in the symbol storage area using the process of <Function 180>.
[Notes] ■In standard mode, use this function when printer is “at the beginning of a line,” or “there is no data in the
print buffer.”
■The symbol size that exceeds the print area cannot be printed.
■If there is any error described below in the data of the symbol storage area, it cannot be printed.
• There is no data (Function 180 is not processed).
• If the data of the symbol storage area is more than the data allowed by specified model and data
compaction mode. (This case is an abnormal number of data.)
• The four data compaction modes are listed below (in order of compaction rate). Automatically selects
best compaction mode by the data of the symbol storage area.
– Numerical mode
– Alphanumeric mode
– Kanji mode
– 8-Bit Byte Mode
■The following data are added automatically by the encode processing.
• Position Detection Patterns
• Separators for Position Detection Patterns
• Timing Patterns
