2D symbol type	Description
Standard PDF417	Converts the string into UTF-8, processes the escape sequence(s), and encodes the data. The maximum number of code words in the data area is 928, the maximum number of code words in a single stage is 30, and the maximum number of stages is 90.
Truncated PDF417
QR Code Model 1	Converts the string into JIS, processes the escape sequence(s), and encodes the data by choosing the data type from the following: Figure: 0 to 9 Alphanumeric: 0 to 9, A to Z, space, $, %, *, +, -, ., /, : Kanji character: Shift JIS value 8-bit byte data: 0X00 to 0xff
QR Code Model 2
Micro QR Code2
MaxiCode Mode 2	Converts the string into UTF-8, processes the escape sequence(s), and encodes the data. In Mode 2 or 3, if the first data is ][)>\x1e01\x1dyy ("yy" is a 2-digit figure), this is processed as the message header and the second and succeeding data sequence is processed as the primary message. Otherwise, the primary message starts with the fist data. For the mode 2, specify the primary message in the following format: Postal code (1- to 9-digit number) GS: (\x1d) ISO country code (1- to 3-digit number) GS: (\x1d) Service class code (1- to 3-digit number) For the mode 3, specify the primary message in the following format: Postal code (data which can be converted with 1 to 6 code sets A) GS (\x1d) ISO country code (1- to 3-digit figure) GS (\x1d) Service class code (1- to 3-digit number)
MaxiCode Mode 3
MaxiCode Mode 4
MaxiCode Mode 5
MaxiCode Mode 6
GS1 DataBar Stacked	Converts the string into UTF-8, processes the escape sequence(s), and encodes the data. Specify a 13-digit product ID (GTIN) excluding the application ID (AI) and check digit.
GS1 DataBar Stacked Omnidirectional
GS1 DataBar Expanded Stacked	Converts the string into UTF-8, processes the escape sequence(s), and encodes the data. The application ID (AI) can be put in parentheses. The parentheses are used as print characters for HRI and not encoded as data. To encode the following characters, specify the corresponding 2-digit code starting with { : FNC1: {1 (: {( ): {)
Aztec Code	Converts the string into UTF-8, processes the escape sequence(s), and encodes the data.
DataMatrix	Converts the string into UTF-8, processes the escape sequence(s), and encodes the data.

Supplementary explanation

Use the addSymbol method at the beginning of a line.
In the page mode, a 2D symbol is printed at the current print position with the lower-left dot of the 2D symbol as the reference point.
Specify a string in accordance with the type of the 2D symbol specified in type. The 2D symbol is not printed if the string specified in data does not match the 2D symbol type specified in type.
Micro QR Code does not support LEVEL_H.
Specify a constant in accordance with the 2D symbol type specified in type.
When MaxiCode or 2D GS1 DataBar is specified in data, specify LEVEL_DEFAULT.
