PowerShell Print Server remove checkmark from print share "List in the Directory"

Question

I needed to remove the checkmark in the "List in the directory" box under printer queue sharing for several hundred print queues on multiple Windows 2003 print servers.  I ended up doing it manually because I could not figure out how to do it with
PowerShell.  Would like to be prepared for next time and learn a bit more about PowerShell.  Scripting newbie.  Anyone able to get me started?  Couldn't find the registry key pertaining to the setting though I could find it under get-wmiobject
- class win32_printer ... -property published.  Have googled for 2 days.  Most of the scripts suggestions that seem to apply are a bit more extensive and complicated than I am willing to tackle with my experience level.

Answer 1

Great code. I wanted the opposite (to enable it) so I wrote this - which checks to see if the printer has a . in the portname (which for me shows it has an IP address) and to see that it's not already shared.
$printers = Get-WMIObject -class Win32_Printer -computer localhost
foreach ($printer in $printers) {
IF ($Printer.PortName.Contains(".") -and $printer.published -eq $false) {
$printer.Name + " : " + $printer.published
$printer.published = $true
$printer.put()
