怎样获取网络打印机的打印记录[已结贴,结贴人:swife]

发表于：2007-06-19 14:12:15 楼主

我想获取以下记录
打印时间/打印机器/页数/....

如果想得到各打印作业的状态，通常我们可以通过调用以下api:

　　　openprinter

　　　getprinter

　　　enumjobs

　　　closeprinter

　　目前在微软的网站上没有现成的关于以上api调用的vb代码，但有一篇vc的示例代码，您可以参考一下：

　　　howto: get the status of a printer and a print job
　　　（http://support.microsoft.com/support/kb/articles/q160/1/29.asp）

　　另外，您还可以试一下adsi中的iadsprintqueueoperations和iadsprintjoboperations接口。具体信息您可以参考以下文档：

　　　http://msdn.microsoft.com/library/default.asp?url=/library/en-us/netdir/adsi/iadsprintjoboperations.asp?frame=true

　　它需要win2000及以后版本或装了active directory client extension的winnt 4.0sp6a/win95/98/me来运行。关于active directory client extension的安装信息，您可以参考以下文档：

　　　http://www.microsoft.com/windows2000/server/evaluation/news/bulletins/adextension.asp
