禁用打印机的“双向通信"? [英] Disable 'Bidirectional communication' for a printer?

问题描述

如何使用 powershell 禁用双向通信"?

How do you disable 'Bidirectional communication' using powershell?

运行时可以看到EnableBIDI:

get-WmiObject -class Win32_printer | fl *

但是当我尝试这个时，它说没有找到该属性?

But when I try this, it says the property was not found?

Set-PrinterProperty -PrinterName "Some Printer" -PropertyName "EnableBIDI" -Value $False

推荐答案

您正在混合来自两个不同 WMI 类的属性.Set-PrinterProperty 操作来自 root/standardcimv2 命名空间的未记录的 MSFT_PrinterProperty 类，它具有与 Win32_Printer 类 在您之前的命令中.

You are mixing properties from two different WMI classes. Set-PrinterProperty manipulates instances of the undocumented MSFT_PrinterProperty class from the root/standardcimv2 namespace, which has different properties than the Win32_Printer class in your previous command.

相反，操作 Win32_Printer 类的所需实例，因为它具有您想要的属性，然后调用 Put() 提交更改.这在以高程运行时对我有用:

Instead, manipulate the desired instance of the Win32_Printer class since that has the property you want, then call Put() to commit the change. This works for me when run with elevation:

$printer = Get-WmiObject -Class 'Win32_Printer' -Filter 'Name = ''My Printer Name'''
$printer.EnableBIDI = $false
$printer.Put()

使用较新的CimCmdlets 模块，您可以使用 Get-CimInstance 以类似方式进行更改 和 Set-CimInstance cmdlet...

Using the newer CimCmdlets module you can make that change in similar fashion using the Get-CimInstance and Set-CimInstance cmdlets...

$printer = Get-CimInstance -ClassName 'Win32_Printer' -Filter 'Name = ''My Printer Name'''
$printer.EnableBIDI = $false
Set-CimInstance -InputObject $printer

...或将其简化为单个管道...

...or simplify it to a single pipeline...

Get-CimInstance -ClassName 'Win32_Printer' -Filter 'Name = ''My Printer Name''' `
    | Set-CimInstance -Property @{ EnableBIDI = $false }

...甚至将其简化为单个 cmdlet 调用...

...or even simplify it to a single cmdlet invocation...

Set-CimInstance -Query 'SELECT * FROM Win32_Printer WHERE Name = ''My Printer Name''' -Property @{ EnableBIDI = $false }
