如何在.NET 中获取打印机信息？

发布于 2024-07-08 20:33:20 字数 108 浏览 9 评论 0原文

在标准 PrintDialog 中，有四个与所选打印机关联的值：Status、Type、Where 和 Comment。

如果我知道打印机的名称，如何在 C# 2.0 中获取这些值？

正如 dowski 建议的，您可以使用 WMI 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);
    }
}

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.

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);
    }
}

这应该可以工作。

using System.Drawing.Printing;

...

PrinterSettings ps = new PrinterSettings();
ps.PrinterName = "The printer name"; // Load the appropriate printer's setting

之后，各种可以读取 PrinterSettings 的属性。

请注意，ps.isValid() 可以查看打印机是否确实存在。

编辑：一则补充评论。 Microsoft 建议您使用 PrintDocument 并修改其 PrinterSettings，而不是直接创建 PrinterSettings。

This should work.

using System.Drawing.Printing;

...

PrinterSettings ps = new PrinterSettings();
ps.PrinterName = "The printer name"; // Load the appropriate printer's setting

After that, the various properties of PrinterSettings can be read.

Note that ps.isValid() can see if the printer actually exists.

Edit: One additional comment. Microsoft recommends you use a PrintDocument and modify its PrinterSettings rather than creating a PrinterSettings directly.

仅供参考，此处是打印机 ManagementObject 的所有可用属性的列表。

usage: printer.Properties["PropName"].Value

Just for reference, here is a list of all the available properties for a printer ManagementObject.

usage: printer.Properties["PropName"].Value

何必那么矫情 2024-07-15 20:33:21

请注意 dowski 和 Panos 所引用的文章 (MSDN Win32_Printer）可能有点误导。

我指的是大多数数组的第一个值。有的以1开头，有的以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"
};

而另一方面，“ErrorState”表中的第一个值是 0，因此，你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"
};

顺便说一句，
“PrinterState”已过时，但您可以使用“PrinterStatus”。

Please notice that the article that dowski and Panos was reffering to (MSDN Win32_Printer) can be a little misleading.

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:

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:

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".

我已经很长时间没有在 Windows 环境中工作了，但我建议您查看使用 WMI。

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）。

http://msdn.microsoft.com/ en-us/library/System.Printing(v=vs.110).aspx

检索打印机队列和第一个作业的状态的示例。

var queue = new LocalPrintServer().GetPrintQueue("Printer Name");
var queueStatus = queue.QueueStatus;
var jobStatus = queue.GetPrintJobInfoCollection().FirstOrDefault().JobStatus

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).

http://msdn.microsoft.com/en-us/library/System.Printing(v=vs.110).aspx

An example to retrieve the status of the printer queue and first job..

var queue = new LocalPrintServer().GetPrintQueue("Printer Name");
var queueStatus = queue.QueueStatus;
var jobStatus = queue.GetPrintJobInfoCollection().FirstOrDefault().JobStatus

作为 WMI 的替代方案，您可以通过点击 WinSpool.drv（即 Windows API）来获得快速准确的结果 - 您可以获得接口、结构和结构的所有详细信息。来自 pinvoke.net 的常量，或者我已将代码放在 http://delradiesdev.blogspot.com/2012/02/accessing-printer-status-using-winspool.html
