Deleted printers keeps coming back - and multiply ... driving me nuts :(

Clients:

All my users logs onto Windows Server 2012 Remote Desktop Host Server, so there's absolutely nothing on the client machines - they are core windows 7/8 installations.

Printeserver:

I have one printserver (SVFREJA) that has shared these 4 printers:

• TAA - Print 1
• TAA - Print 2
• HAD - Print 1
• HAD - Print 2

Problem:

When my clients logs onto their RDSH, they will sometimes get one of the four printers, sometimes them all, sometimes none and very often they have multiple of the same printer (where most of them doesn't work) like this:

I've tried creating this script:

Set objWMIService = GetObject("winmgmts:\\.\root\cimv2")
Set colPrinters = objWMIService.ExecQuery ("Select * From Win32_Printer")

If colPrinters.Count <> 0 Then 'If there are some network printers
    Dim s
    s = ""
        For Each objPrinterInstalled In colPrinters ' For each network printer
        s = s + objPrinterInstalled.Name + chr(13)
        Next
    msgbox s
End if

... and with all the printers on the image above, this is the result of running the script:

(there's none of the printers from the image recognized by the script).

If I try to delete a printer, then it just pops up again.

How I set up the printers:

I use GPO:

Computer Configuration...

• Windows Components/Remote Desktop Services/Remote Desktop Session Host/Printer Redirection/Do not set default client printer to be default printer in a session = Enabled 

User Configuration...

• Preferences/Control Panel Settings/Printers/Shared Printer: Delete all shared printers (Order 1)

• Preferences/Control Panel Settings/Printers/Shared Printer: \\SVFREJA\TAA - Print 1 (Order 2)

• Preferences/Control Panel Settings/Printers/Shared Printer: \\SVFREJA\TAA - Print 2 (Order 3)

• Preferences/Control Panel Settings/Printers/Shared Printer: \\SVFREJA\HAD - Print 1 (Order 4)

• Preferences/Control Panel Settings/Printers/Shared Printer: \\SVFREJA\HAD - Print 2 (Order 5)

Question:

1. How do I rid of the ophaned printers?
2. Why isn't the printers set up correctly when the user logs on? It's kinda random.

Thanks
