根据条件打印概述

根据条件打印可用于设置文档对象打印依据的具体条件。请考虑以下示例：

您正在使用相同的基本框架为两个独立的运动团队（A 队和 B 队）经营专业体育用品店。除了标志不同，发货标签的其他部分都相同。通过使用根据条件打印并监视模板上的具名数据源的值，您可以对两种发货标签使用相同的模板。打印 A 队的运输标签时，标签上就会出现 A 队的标志。同样，打印 B 队的运输标签时，会打印相应的标志。

Conditional statements are defined by using the When to Print dialog and can be based on a complex expression or on the value of a single data source. All conditional statements in BarTender contain a data source that is followed by an operator and an optional value. 复杂表达式也可以包含一个或多个条件连接符。 The following charts describe the functionality of these components.

	条件连接符	描述
	And	When two or more conditional statements are joined by an "And" joiner, all conditional statements must be met to run the instruction.
	Or	When two or more conditional statements are joined by an "Or" joiner, one or more of the conditional statements must be met to run the instruction.
	Not And	When two or more conditional statements are joined by a "Not And" joiner, all conditional statements must be unmet to run the instruction.
	Not Or	When two or more conditional statements are joined by a "Not Or" joiner, one or more of the conditional statements must be unmet to run the instruction.

运算符

Operators determine the relationship that you want between the data source and the value. 条件表达式的结构与句子类似，即“主语（数据源）”“动词（运算符）”“宾语（值）”。以下条件表达式运算符可用于控制对象、图层、模板或背景的打印，以及数据源的抑制：

条件运算符	有效输入	示例
Equals	除“时间”、“二进制”和“图片”外的所有类型	[数据源] Equals <值>
Does not equal	除“时间”、“二进制”和“图片”外的所有类型	[数据源] Does Not Equal <值>
Is greater than	除“时间”、“二进制”和“图片”外的所有类型	[数据源] Is greater than <值>
Is greater than or equal to	除“时间”、“二进制”和“图片”外的所有类型	[数据源] Is greater than or equal to <值>
Is less than	除“时间”、“二进制”和“图片”外的所有类型	[数据源] Is less than <值>
Is less than or equal to	除“时间”、“二进制”和“图片”外的所有类型	[数据源] Is less than or equal to <值>
Is between	除“时间”、“二进制”和“图片”外的所有类型	[数据源] Is between <值 1> and <值 2>
