如何获取计算机中所有打印机的列表

查看静态 系统。绘图。打印。打印设置。安装打印机属性。

它是系统上所有已安装打印机的名称列表。

试试这个:

foreach (string printer in System.Drawing.Printing.PrinterSettings.InstalledPrinters)
{
MessageBox.Show(printer);
}

如果你需要更多的信息而不仅仅是打印机的名称，你可以使用 System.Management API 来查询它们:

var printerQuery = new ManagementObjectSearcher("SELECT * from Win32_Printer");
foreach (var printer in printerQuery.Get())
{
var name = printer.GetPropertyValue("Name");
var status = printer.GetPropertyValue("Status");
var isDefault = printer.GetPropertyValue("Default");
var isNetworkPrinter = printer.GetPropertyValue("Network");


Console.WriteLine("{0} (Status: {1}, Default: {2}, Network: {3}",
name, status, isDefault, isNetworkPrinter);
}

在 ASP.NET 中获取网络和本地打印机列表

此方法使用 Windows 管理规范或 WMI 接口。它是一种用于获取在 Windows 操作系统上运行的各种系统(硬件)的信息的技术。

private void GetAllPrinterList()
{
ManagementScope objScope = new ManagementScope(ManagementPath.DefaultPath); //For the local Access
objScope.Connect();


SelectQuery selectQuery = new SelectQuery();
selectQuery.QueryString = "Select * from win32_Printer";
ManagementObjectSearcher MOS = new ManagementObjectSearcher(objScope, selectQuery);
ManagementObjectCollection MOC = MOS.Get();
foreach (ManagementObject mo in MOC)
{
lstPrinterList.Items.Add(mo["Name"].ToString());
}
}

列出网络和本地打印机的应用演示

您也可以使用 LocalPrintServer类

public List<string>  InstalledPrinters
{
get
{
return (from PrintQueue printer in new LocalPrintServer().GetPrintQueues(new[] { EnumeratedPrintQueueTypes.Local,
EnumeratedPrintQueueTypes.Connections }).ToList()
select printer.Name).ToList();
}
}

如文件所述: 不支持在 Windows 服务或 ASP.NET 应用程序或服务中使用 System.Printing命名空间中的类。

如果您使用的是 MVC C # ，这是处理打印机和串行端口下拉菜单的方法。

using System.Collections.Generic;
using System.Linq;
using System.IO.Ports;
using System.Drawing.Printing;


public class Miclass
{
private void AllViews()
{
List<PortClass> ports = new List<PortClass>();
List<Printersclass> Printersfor = new List<Printersclass>();
string[] portnames = SerialPort.GetPortNames();
/*PORTS*/
for (int i = 0; i < portnames.Count(); i++)
{
ports.Add(new PortClass() { Name = portnames[i].Trim(), Desc = portnames[i].Trim() });
}
/*PRINTER*/
for (int i = 0; i < PrinterSettings.InstalledPrinters.Count; i++)
{
Printersfor.Add(new Printersclass() { Name = PrinterSettings.InstalledPrinters[i].Trim(), Desc = PrinterSettings.InstalledPrinters[i].Trim() });
}
}
}
public class PortClass
{
public string Name { get; set; }
public string Desc { get; set; }


public override string ToString()
{
return string.Format("{0} ({1})", Name, Desc);
}
}
public class Printersclass
{
public string Name { get; set; }
public string Desc { get; set; }


public override string ToString()
{
return string.Format("{0} ({1})", Name, Desc);
}
}
