1. 配置打印模板
【基礎(chǔ)設(shè)置（集團）】-【打印配置】
image.png
實體：需要打印的實體
數(shù)據(jù)類型：常量、字段（取值來自實體）
字段：實體下的字段
字段（公式）：通過公式取值
打印類型：文本、條碼载弄、二維碼
數(shù)據(jù)：當(dāng)數(shù)據(jù)類型為常量時需要維護常量的值
PosX:數(shù)據(jù)在紙張上的橫軸位置單位dot
PosY:數(shù)據(jù)在紙張上的豎軸位置單位dot
字段高度：當(dāng)打印類型為文本時有效
對齊方式：
條碼類型：當(dāng)打印類型為條碼時有效
數(shù)據(jù)長度/小數(shù)位數(shù)：數(shù)據(jù)為字符串時用于截取字符串的長度，數(shù)據(jù)為數(shù)字時小數(shù)位數(shù)有效
日期格式：數(shù)據(jù)為日期時對日期進行格式化
數(shù)據(jù)截取類型：當(dāng)數(shù)據(jù)為字符串時截取字符串（從左截取撵颊、從右截扔罟ァ）
1.1. 字段
用于設(shè)置數(shù)據(jù)的取值來源，使用字段（公式）實現(xiàn)更加靈活的取值方式倡勇。
1.2. 字段（公式）

- 由于未實現(xiàn)字段的樹形參照逞刷，通過此字段取層級深的數(shù)據(jù)比如取標(biāo)準(zhǔn)銷售-客戶-立賬條件的名稱，字段（公式）：
OrderBy.Customer.ARConfirmTerm.Name - 通過中間表取數(shù)妻熊，取收款計劃的收款的整單金額夸浅，字段（公式）：
Entity:UFIDA.U9.SM.InstalmentRecSchedule.InstalmentRecSchedule:DocID=ID:Status - 通過（OrderBy.Customer.ARConfirmTerm.Name+驗）可以實現(xiàn)動態(tài)數(shù)據(jù)（OrderBy.Customer.ARConfirmTerm.Name）+靜態(tài)數(shù)據(jù)（驗）
2. 安裝WebPrint、配置打印機IP（打印機連接的電腦的IP）
2.1. 安裝WebPrint
- WebPrint下載地址：
https://s3.cn-north-1.amazonaws.com.cn/godex/GXDXqOixaOHR6gZvVnUBgQ.file?v01 - 只有連接打印機的電腦需要安裝WebPrint,電腦安裝好WebPrint并連接好打印機后在U9配置打印機IP
2.2. 配置打印機IP
【基礎(chǔ)設(shè)置（集團）】-【公共設(shè)置】-【參數(shù)設(shè)置】配置【連接打印機的電腦的IP地址】
2.3. 網(wǎng)絡(luò)配置
U9服務(wù)器需要可以訪問打印機連接電腦的IP
3. 選擇扔役、修改打印數(shù)據(jù)题篷、打印
3.1. 選擇需要打印的數(shù)據(jù)

選擇需要打印的數(shù)據(jù)點擊打印條碼
3.2. 修改需要打印的數(shù)據(jù)

3.3 調(diào)用打印機
