推荐答案

您的问题的主要问题是我认为我们无法回答.打印机具有一些默认设置，可以通过.NET组件进行设置:

您的打印机在我的商店中存储了默认打印机类不需要的其他属性，如果要获取这些属性，则必须在打印机文档中查找单个产品.

The main problem with your question is I dont think we can answer it. Printers have some default settings that can be set via the .NET assembelies:

Your printer my store additional properties not required by the default printer class, and if you are going to get these then you will have to look in the printer documentation for the individual product.

有没有独立于供应商的方法，尤其是对于直接连接的打印机.由于没有标准和/或接口，因此驱动程序必须遵守此规定.每个供应商都将使用其自己的dll，自己的方法向用户发送此类情况(如果有的话).
对于网络打印机，如果设备支持，则唯一非厂商特定的监视方法是使用SNMP.咨询本文: http://techblog.willshouse.com /2012/01/24/how-to-monitor-canon-printers-with-snmp/ [ http://social.msdn.microsoft.com/Forums/zh/vcgeneral/thread/38280210-406a-4e4e-8d31-f044a59708e2 [使用C#更改打印机设置 [打印机和SafeHandles [

There is no vendor-independent approach, especially for direct attached printers. As there is no standard and/or interface the driver must comply in this matter. Every vendor will use it''s own dll-s, own methods to signal such conditions to the user (if at all).
For network printers the only not vendor-specific approach of monitoring them is using SNMP if the device supports it. Consult this article: http://techblog.willshouse.com/2012/01/24/how-to-monitor-canon-printers-with-snmp/[^]. And only network printers will have an embedded web server, that can be also used to retrieve this kind of information. But USB printers do not have this either.

Update: there is something you could follow. The PRINTER_INFO_2 structure contains a status field that is near of what you want. You need to call out to unmanaged api.
