.SYNOPSIS Gets the default printer of a remote machine. .DESCRIPTION Gets the default printer of a remote machine of a specfifc user, including Shared Server Printers. .PARAMETER ComputerName Use this paramter to specify the computer(s) you want to run the command aganist using its name or IPAddress. .PARAMETER SamAccountName This paramter allows you to only grab the default printers of the specifed user(s). This value is evaluated against the leaf of the localpath from Win32_UserProfile class .PARAMETER Quiet This parameter prevents errors being generated if the computer is unreachable .EXAMPLE PS C:\> Get-DefaultPrinter -ComputerName Client01v PrintServer PrinterName UserName ComputerName ----------- ----------- -------- ------------ Local OneNote pwsh.cc Client01v This example gets the default printer of the only logged in user on Client01v. .EXAMPLE PS C:\>Get-DefaultPrinter -ComputerName Client01v,dc01v PrintServer PrinterName UserName ComputerName ----------- ----------- -------- ------------ Local OneNote pwsh.cc Client01v Local Microsoft Print to PDF Administrator dc01v PS C:\> Get-DefaultPrinter -ComputerName Client01v,dc01v -SamAccountName pwsh.cc PrintServer PrinterName UserName ComputerName ----------- ----------- -------- ------------ Local OneNote pwsh.cc Client01v In this example it shows how the SamAccountName parameter works by only grabbing default users specified. Only pwsh.cc was returned by the second command even though the current user Administrator had a default printer on dc01v. .EXAMPLE PS C:\>Test-Connection -ComputerName client01v -Count 1 -Quiet False PS C:\Users\Administrator> Get-DefaultPrinter -ComputerName Client01v,dc01v -Quiet PrintServer PrinterName UserName ComputerName ----------- ----------- -------- ------------ Local Microsoft Print to PDF Administrator dc01v In this example we can see how the quiet paramter works, by omitting errors of computers that are unreachable such as Client01v. .INPUTS String .OUTPUTS PsCustomObject SysAdminTool.DefaultPrinter .NOTES Uses WsMan Protocol as default and fallsback to DCOM.
