检查打印机是否支持 postscript

Question

有什么方法可以使用 C# 检查打印机是否支持 postscript？在我对我的文件做任何事情之前，我需要检查这个。

谢谢，巴尔托斯

Answer 1

您可能会使用 WMI，但我不确定此解决方案是否可靠

System.Management.ObjectQuery oq = new System.Management.ObjectQuery("SELECT * FROM Win32_Printer");
ManagementObjectSearcher mos = new ManagementObjectSearcher(oq);
ManagementObjectCollection moc = mos.Get();
foreach( ManagementObject mo in moc )
{

    string name = mo["Name"].ToString();
    string language = mo["DefaultLanguage"].ToString();
    MessageBox.Show(String.Format("Printer: {0} -- Language: {1}", name, language));
}

Lifted from here

更新

在此处查看其他可能相关的字段

Win32_Printer class

特别是uint16 LanguagesSupported[];

Answer 2

我终于使用的代码，稍作改动：

System.Management.ObjectQuery oq = new System.Management.ObjectQuery("SELECT * FROM Win32_Printer");
        ManagementObjectSearcher mos = new ManagementObjectSearcher(oq);
        ManagementObjectCollection moc = mos.Get();
        foreach (ManagementObject mo in moc)
        {

            string name = mo["Name"].ToString();
            var language = mo["LanguagesSupported"];
            Console.WriteLine(String.Format("Printer: {0} -- Language: {1}", name, language==null ? 0 : (language as ushort[])[0]));
        }
