How to get Printer Info in .NET?
提问by Nick Gotch
In the standard PrintDialog there are four values associated with a selected printer: Status, Type, Where, and Comment.
在标准 PrintDialog 中，有四个与选定打印机相关联的值：状态、类型、位置和注释。
If I know a printer's name, how can I get these values in C# 2.0?
如果我知道打印机的名称，如何在 C# 2.0 中获得这些值？

As dowski suggested, you could use WMI to get printer properties. The following code displays all properties for a given printer name. Among them you will find: PrinterStatus, Comment, Location, DriverName, PortName, etc.
正如多夫斯基建议的那样，您可以使用 WMI 来获取打印机属性。以下代码显示给定打印机名称的所有属性。其中您会发现：PrinterStatus、Comment、Location、DriverName、PortName 等。
using System.Management;
...
...
string printerName = "YourPrinterName";
string query = string.Format("SELECT * from Win32_Printer WHERE Name LIKE '%{0}'", printerName);
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
using (ManagementObjectCollection coll = searcher.Get())
{
try
{
foreach (ManagementObject printer in coll)
{
foreach (PropertyData property in printer.Properties)
{
Console.WriteLine(string.Format("{0}: {1}", property.Name, property.Value));
}
}
}
catch (ManagementException ex)
{
Console.WriteLine(ex.Message);
}
}

This shouldwork.
这应该有效。
using System.Drawing.Printing;
...
...
PrinterSettings ps = new PrinterSettings();
ps.PrinterName = "The printer name"; // Load the appropriate printer's setting
After that, the various propertiesof PrinterSettings can be read.
之后，可以读取PrinterSettings的各种属性。
Note that ps.isValid()can see if the printer actually exists.
注意ps.isValid()可以查看打印机是否实际存在。
Edit: One additional comment. Microsoft recommends you use a PrintDocumentand modify its PrinterSettings rather than creating a PrinterSettings directly.
编辑：一个额外的评论。Microsoft 建议您使用PrintDocument并修改其 PrinterSettings，而不是直接创建 PrinterSettings。

Please notice that the article that dowskiand Panoswas reffering to (MSDN Win32_Printer) can be a little misleading.
请注意，dowski和Panos所指的文章( MSDN Win32_Printer) 可能有点误导。
I'm referring the first value of most of the arrays. some begins with 1 and some begins with 0. for example, "ExtendedPrinterStatus" first value in table is 1, therefore, your array should be something like this:
我指的是大多数数组的第一个值。有些以 1 开头，有些以 0 开头。例如，“ ExtendedPrinterStatus”表中的第一个值是 1，因此，您的数组应该是这样的：
string[] arrExtendedPrinterStatus = {
"","Other", "Unknown", "Idle", "Printing", "Warming Up",
"Stopped Printing", "Offline", "Paused", "Error", "Busy",
"Not Available", "Waiting", "Processing", "Initialization",
"Power Save", "Pending Deletion", "I/O Active", "Manual Feed"
};
and on the other hand, "ErrorState" first value in table is 0, therefore, your array should be something like this:
另一方面，“ ErrorState”表中的第一个值是 0，因此，您的数组应该是这样的：
string[] arrErrorState = {
"Unknown", "Other", "No Error", "Low Paper", "No Paper", "Low Toner",
"No Toner", "Door Open", "Jammed", "Offline", "Service Requested",
"Output Bin Full"
};
BTW, "PrinterState" is obsolete, but you can use "PrinterStatus".
顺便说一句，“ PrinterState”已过时，但您可以使用“ PrinterStatus”。

As an alternative to WMI you can get fast accurate results by tapping in to WinSpool.drv (i.e. Windows API) - you can get all the details on the interfaces, structs & constants from pinvoke.net, or I've put the code together at http://delradiesdev.blogspot.com/2012/02/accessing-printer-status-using-winspool.html
作为 WMI 的替代方案，您可以通过进入 WinSpool.drv（即 Windows API）获得快速准确的结果 - 您可以从 pinvoke.net 获取有关接口、结构和常量的所有详细信息，或者我已将代码放在一起在http://delradiesdev.blogspot.com/2012/02/accessing-printer-status-using-winspool.html

I know it's an old posting, but nowadays the easier/quicker option is to use the enhanced printing services offered by the WPF framework (usable by non-WPF apps).
我知道这是一个旧帖子，但现在更简单/更快的选择是使用 WPF 框架提供的增强打印服务（可由非 WPF 应用程序使用）。

An example to retrieve the status of the printer queue and first job..
检索打印机队列和第一个作业状态的示例..
var queue = new LocalPrintServer().GetPrintQueue("Printer Name");
var queueStatus = queue.QueueStatus;
var jobStatus = queue.GetPrintJobInfoCollection().FirstOrDefault().JobStatus
