怎么样获取枚举机器上所有打印机的相关信息（打印机名、IP、型号）

Question

各位大虾，怎么样获取枚举机器上所有打印机的相关信息（打印机名、IP、型号）？

Answer 1

using System.Drawing.Printing; 
listBox1.Items.Clear();
foreach (string printer in PrinterSettings.InstalledPrinters)
{
   listBox1.Items.Add(printer);
} 

Answer 2

名称楼上已经说了。IP对于本机的就没有了，对于网络打印机取名称的前几个字符串，形式一般如下：
\\127.0.0.1\aaaaaa型号不好搞，软件获得的信息都是通过的打印机驱动，它没有型号的信息。只能通过打印机名称判断了（但名称可以手工修改，所以不准确）。

这是一个form的代码,你在form上加一个list就能运行,能获取打印机的所有信息using System;
using System.Collections.Generic;

Answer 4

有这个命名空间
System.Drawing.Printing; 
我觉得就没有问题

Answer 5

通过改变
printInfo = EnumPrinters(PrinterEnumFlags.PRINTER_ENUM_LOCAL);
中的参数可以查看不同范围内的打印机设置,可以挨个测试
如可以改成
printInfo = EnumPrinters(PrinterEnumFlags.PRINTER_ENUM_CONNECTIONS);另外
listBox1.Items.Add(safestring(printInfo[i].pServerName));
                    listBox1.Items.Add(printInfo[i].pShareName);
                    listBox1.Items.Add(printInfo[i].pPrinterName);
                    listBox1.Items.Add(printInfo[i].pPortName);
                    listBox1.Items.Add(printInfo[i].Status);
还有很多信息没显示,可以根据你的需要显示

Answer 6

这个需要使用ManagementObjectSearcher。
如果是检查本地机器的，可以这样：
PrintDocument prtdoc = new PrintDocument();
if (PrinterSettings.InstalledPrinters.Count == 0) //检查有没有安装打印机
         strResult = "No printer installed on your machine.";
else if (prtdoc.PrinterSettings.PrinterName == "<no default printer>") //检查有没有设置默认打印机
{
         strResult = "Please set one printer as default printer.";
}
else if (!prtdoc.PrinterSettings.IsValid) //检测文档的打印设置是否合法
{
         strResult = "Printer Settings is invalid.";
}
