I am using this to attempt to get a list of printers on a remote computer:
Get-WmiObject win32_printer -ComputerName "$oldPcName" The problem is I only get local printers, not those printers from the print server connected to the computer. How can I get a list of the network printers?
My goal is to get a list of network printers on a remote computer, remove them, and add different printers from a different print server.
Thanks

#####This is as far as I could get with it. I always turn off UAC and Enable Scripts in the beginning and turn them back on ant the end. The summary of this script will give you the new network Printer paths and the users default printers. It also deletes the users old network printers. With powershell versions before windows 8 and server 2012, you would have to create a logon script to add the new printers and mark the default printer using WMI commands. Use could also use a csv file with a list of computer names as an input if you wish to run this command on multiple computers. It would look something like...
$csv = Import-csv -Path pathofcsvfile
foreach ($line in $csv) {
#With a bracket at the end to run through each computer in the list...This is all much easier with newer versions of Windows as they have the Get-printers cmdlet...
Hopefully that can get you started... I would love to see someone finish this script as I have not had the time at work to do so...

To see networked printers, I read the registry
Function InstalledPrinters ($ComputerName) { Invoke-Command -ComputerName $ComputerName -ScriptBlock { $InstalledPrinters = Get-ChildItem "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Connections" $InstalledPrinters | Add-Member -Name 'PrinterName' -MemberType NoteProperty -Value "" Foreach ($InstalledPrinter in $InstalledPrinters) {$InstalledPrinter.PrinterName = $InstalledPrinter.GetValue("Printer").split("\")[3]} Return $InstalledPrinters | sort PrinterName | select PSComputerName, PrinterName } } To remove a network printer:
rundll32.exe PRINTUI.DLL PrintUIEntry /gd /c\\$ComputerName /n\\$PrintServer\$PrinterName Gw /qTo install a network printer:
rundll32.exe PRINTUI.DLL PrintUIEntry /ga /c\\$ComputerName /n\\$PrintServer\$PrinterName Gw /qHmm. There might be a way to do this with a Raspberry Pi. You connect the raspberry pi to the printer and to wifi, you enable port forwarding for ssh or use VNC viewer to access the Raspberry Pi. Using VNC, you can transfer files to the Raspberry Pi over the network. You then get the Raspberry Pi to print out the files you want.
Its not the best straightforward idea, but thats the only way I know of. Raspberry Pi are also very cheap. Latest model only cost £35. If you wanted to do this way, you would need to make a VNC account, then add your Raspberry Pi into your VNC address book. To do this you need to have Raspbian Desktop, and login to your VNC account on the raspberry Pi.
