在没有prnadmin.dll的情况下使用powershell安装“打印机窗体”？

Question

由于来自Microsoft的最新安全更新已将Jet OLEDB Provider无法使用，因此我必须重写几个较老的VBScript。

是否有更好的方法在Windows Server 2008 R2和2012 R2上安装打印机表单，然后通过regsvr32/COM/VBscript调用过时的prnadmin.dll？

prnadmin.dll最初与Windows Server 2000 Resource Kit一起引入，我想将整个脚本迁移到PowerShell。

不幸的是我找不到模块PrintManagement内的任何有用的PowerShell cmdlet。那么如何使用PSH将自定义表单添加到打印机服务器？

添加系统表单定义的编程方法是致电AddForm。我知道这个电话没有很好的包装，但是P/Invoking为AddForm。我写了一个快速包装和posted it on GitHub。

实施例使用包装：

Windows PowerShell 
Copyright (C) 2016 Microsoft Corporation. All rights reserved. 

PS C:\Drop> Import-Module .\PowershellPrinterFormsModule.dll 
PS C:\Drop> Add-SystemForm -Name 'Demo User Form try 1' -Units Inches -Size '4,5' 
PS C:\Drop> Add-SystemForm -Name 'Demo User Form try 2' -Units Inches -Size '4,5' -Margin '0.25,0.5' 
PS C:\Drop> Add-SystemForm -Name 'Demo User Form try 3' -Units Millimeters -Size '80,50' -Margin '10,10,0,0' 

实际P /调用调用AddForm：

SafePrinterHandle hServer; 
if (!OpenPrinter(null, out hServer, IntPtr.Zero)) 
{ 
    throw new Win32Exception(); 
} 
using (hServer) 
{ 
    var form = new FORM_INFO_1() 
    { 
     Flags = 0, 
     Name = this.Name, 
     Size = (SIZEL)pageSize, 
     ImageableArea = (RECTL)imageableArea 
    }; 

    if (!AddForm(hServer, 1, ref form)) 
    { 
     throw new Win32Exception(); 
    } 
}

     if (!OpenPrinter(null, out hServer, IntPtr.Zero))

     } 
     return hServer; 
    }
