使用Java打印到非默认打印机的标签打印机

标签: java pdf printing

我需要打印到标签打印机。我在互联网上找到了下面的代码,并试图根据我的需要对其进行修改。当标签打印机是系统中的默认打印机时,它可以正常工作,但是当我将其他打印机设置为默认打印机时,它无法正确打印。 在下面链接的图片中,可以看到默认情况下的结果(右边的那个),第一次尝试时不是默认值(中间的),第二次尝试时不是默认值。 我需要正确打印打印机是否是默认打印机,因为这将是我们将发布给客户的软件的一部分。我的问题是:是否有任何特定的属性或命令我应该发送到打印机,以便在不是默认打印机时正确打印?或者如何在打印之前从我的代码中将该打印机设置为默认打印机,然后在打印完成后恢复默认打印机? 图片链接(https://lh4.googleusercontent.com/-jBa7bA77ik0/URplehZYVIE/AAAAAAAAQWg/bO4EE3wepjg/s279-c/21213
