是否有可能将虚拟打印机与物理打印机不同? [英] Is there a possibility to differ virtual printer from physical one?

问题描述

我有一份在 WinXP 中可用的所有打印机的列表.我需要代码(最好是 .NET)来从这个列表中过滤掉所有的虚拟打印机.有可能吗?我分析了 Win32_Printer wmi 类的所有属性，但没有找到合适的.

I have a list of all printers available in WinXP. I need the code (ideally .NET) to filter out all the virtual printers from this list. Is it possible to do? I analyzed all the properties of Win32_Printer wmi class but can't see any suitable one.

推荐答案

我知道这是一个老问题，但这个答案可能对遇到同样问题的人有所帮助.

I know this is an old question but this answer may be helpful to someone with the same problem.

如果我对虚拟打印机"的理解是正确的.您可以检查 WMI 属性PrintProcessor"并忽略winprint".据我所知，这将忽略所有基于 Windows 7 软件的打印机选项.下面是一些示例代码来演示这一点.返回打印机名称.

If my understanding of a "virtual printer" is correct. You could check the WMI property "PrintProcessor" and ignore "winprint". To my knowledge this will ignore all of Windows 7 software based printer options. Here is some sample code to demonstrate that. Returns the printer name.

        using System.Management;

        try
        {
            ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\CIMV2", "SELECT * FROM Win32_Printer");

            foreach (ManagementObject obj in searcher.Get())
            {
                if(obj != null)
                {
                    if(obj["PrintProcessor"].ToString().ToUpper() != "WINPRINT")
                    {
                        Console.WriteLine(obj["Name"]);
                    }
                }
            }
        }
        catch (ManagementException e)
        {
            MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
        }
