1. 配置打印模板
【基础设置（集团）】-【打印配置】
image.png
实体：需要打印的实体
数据类型：常量、字段（取值来自实体）
字段：实体下的字段
字段（公式）：通过公式取值
打印类型：文本、条码、二维码
数据：当数据类型为常量时需要维护常量的值
PosX:数据在纸张上的横轴位置单位dot
PosY:数据在纸张上的竖轴位置单位dot
字段高度：当打印类型为文本时有效
对齐方式：
条码类型：当打印类型为条码时有效
数据长度/小数位数：数据为字符串时用于截取字符串的长度，数据为数字时小数位数有效
日期格式：数据为日期时对日期进行格式化
数据截取类型：当数据为字符串时截取字符串（从左截取、从右截取）
1.1. 字段
用于设置数据的取值来源，使用字段（公式）实现更加灵活的取值方式。
1.2. 字段（公式）

- 由于未实现字段的树形参照，通过此字段取层级深的数据比如取标准销售-客户-立账条件的名称，字段（公式）：
OrderBy.Customer.ARConfirmTerm.Name - 通过中间表取数，取收款计划的收款的整单金额，字段（公式）：
Entity:UFIDA.U9.SM.InstalmentRecSchedule.InstalmentRecSchedule:DocID=ID:Status - 通过（OrderBy.Customer.ARConfirmTerm.Name+验）可以实现动态数据（OrderBy.Customer.ARConfirmTerm.Name）+静态数据（验）
2. 安装WebPrint、配置打印机IP（打印机连接的电脑的IP）
2.1. 安装WebPrint
- WebPrint下载地址：
https://s3.cn-north-1.amazonaws.com.cn/godex/GXDXqOixaOHR6gZvVnUBgQ.file?v01 - 只有连接打印机的电脑需要安装WebPrint,电脑安装好WebPrint并连接好打印机后在U9配置打印机IP
2.2. 配置打印机IP
【基础设置（集团）】-【公共设置】-【参数设置】配置【连接打印机的电脑的IP地址】
2.3. 网络配置
U9服务器需要可以访问打印机连接电脑的IP
3. 选择、修改打印数据、打印
3.1. 选择需要打印的数据

选择需要打印的数据点击打印条码
3.2. 修改需要打印的数据

3.3 调用打印机
