Values

UPC_A → const BarCodeType

要求12位数字（最后⼀位校验位）

UPC_E → const BarCodeType

要求8位数字（最后⼀位校验位）

JAN13_EAN13 → const BarCodeType

JAN13_EAN13

JAN8_EAN8 → const BarCodeType

JAN8_EAN8

CODE39 → const BarCodeType

最⻓打印13个数字

ITF → const BarCodeType

要求输⼊数字，且有效⼩于14位，必须是偶数位

CODABAR → const BarCodeType

要求0-9及6个特殊字符，最⻓打印18个数字

CODE93 → const BarCodeType

最⻓打印17个数字

CODE128 → const BarCodeType

Code128分三类：

• A类：包含⼤写字⺟、数字、标点等；
• B类：⼤⼩写字⺟，数字；
• C类：纯数字，复数字符，若为单数位，最后⼀个将忽略；

接⼝默认使⽤B类编码，若要使⽤A类、C类编码需在内容前⾯加“{A”、“{C”，例 如：“{A2344A”，”{C123123”，”{A1A{B13B{C12”。
