Powershell script to list printers with WPK

[fawkers]

Hi There

 

I've been trying to get this powershell script to work it should produce a windows with a list of printers, It's using the powershell plus kit from the MSDN site (also in the win 7 resource kit).

 

$DetectedErrorState="unknown","other","No Error","Low Paper","No Paper",`
"Low Toner","No Toner","Door OPen","Jammed","Offline","Service Requested",`
"output Bin Full"

$PrinterStatus="Other","Unknown","Idle","Printing","Warming Up","Stopped Printing","Offiline"

#function test{
#    $class = "win32_printer"
#    $printers = Get-WmiObject -Class $Class -ComputerName "" -Credential \
#    foreach($p in $printers){
#        output $p.Name, $DetectedErrorState[$p.DetectedErrorState], $PrinterStatus[$p.PrinterStatus]
#    }
#}


New-ListView -Width 350 -Height 350 -DataBinding @{
   ItemsSource = New-Binding -IsAsync -UpdateSourceTrigger PropertyChanged -Path Output
} -View {
   New-GridView -AllowsColumnReorder -Columns {
       New-GridViewColumn "Name" 
       }
} -DataContext {
   Get-PowerShellDataSource -Script {
       #Get-Process | ForEach-Object { $_ ; Start-Sleep -Milliseconds 25 }
       Get-WmiObject -Class $Class -ComputerName "\ |`
       ForEach-Object {
           $_.Name
       }
   }
} -On_Loaded {
   Register-PowerShellCommand -Run -In "0:0:15" -ScriptBlock {
       $window.Content.DataContext.Script = $window.Content.DataContext.Script
   }
} -asjob 

 

If you look in the -DataContext section the commented out line will work, but the four lines below it don't. Can anyone see whats going wrong?

 

Thanks

Hello Everyone

 

Got this from technet

 

New-ListView -Width 350 -Height 350 -DataBinding @{
   ItemsSource = New-Binding -IsAsync -UpdateSourceTrigger PropertyChanged -Path Output
} -View {
   New-GridView -AllowsColumnReorder -Columns {
       New-GridViewColumn "Name" 
       New-GridViewColumn "PrinterStatus"
       }
} -DataContext {
   Get-PowerShellDataSource -Script {
$list = @()
$PrinterStatus="Other","Unknown","Idle","Printing","Warming Up","Stopped Printing","Offiline"


Get-WmiObject -Class Win32_Printer | 
ForEach-Object {
$list += New-Object Object | Add-Member NoteProperty Name $_.name -passthru | Add-member NoteProperty PrinterStatus $PrinterStatus[$_.PrinterStatus-1] -passthru
}
foreach ($item in $list)
{ 
$item
}


   }
} -On_Loaded {
   Register-PowerShellCommand -Run -In "0:0:15" -ScriptBlock {
       $window.Content.DataContext.Script = $window.Content.DataContext.Script
   }
} -asjob 

 

which works however if you cange the -script block to

 

   Get-PowerShellDataSource -Script {
$list = @()
$PrinterStatus="Other","Unknown","Idle","Printing","Warming Up","Stopped Printing","Offiline"

$password = (Read-Host -AsSecureString)
$user = New-Object Management.Automation.PSCredential ("olympus\ap.admin", $password)

Get-WmiObject -Class Win32_Printer -computername "shsg-d02-prt01" -Credential $User | 
ForEach-Object {
$list += New-Object Object | Add-Member NoteProperty Name $_.name -passthru | Add-member NoteProperty PrinterStatus $PrinterStatus[$_.PrinterStatus-1] -passthru
}
foreach ($item in $list)
{ 
$item
}


   }

 

to allow for a remote computer it doesn't work any more... if anyone has any ideas...

 

 

Thanks
