哪位大神知道C#中如何获取打印机的打印结果。不是当前打印机状态。十万火急，万分感谢
C#如何能获取到打印机一个打印任务完成后的打印结果的状态。就是打印成功还是失败的状态。打印机API中有支持的方法么？ --------------------编程问答-------------------- 对Windows打印系统(spooler)来说，把打印任务发给打印机就算打印完成了，Spooler API只能查到这里。
对打印机来说，打印机具体打印的时候，可能还会出现缺纸，卡纸，缺墨等问题。
某些打印机（包括驱动程序）支持双向通讯，这种情况下spooler可能汇报更具体的打印状态。
打印机的状态查询和任务查询，没有统一的接口。有些打印机支持PJL查询，有些支持SNMP查询，有些使用内部协议。

版主威武啊

想要获取的是在打印过程完毕之后打印队列里面已经打印完毕的某条信息的成功状态。补充：.NET技术 , C#
