How to "uninstall" a printer using a logon / startup script


I recently made some changes to some printers on our network, which involved the removal of one printer, the installation of a new one, and the renaming of the an existing one. Now when a user logs on, there's a list of four printers, two of which are redundant. It is possible to delete the redundant printers by adding a line to a log on script? I used the net script to map the printers, as below

Dim net
Set net = CreateObject("WScript.Network")
net.AddWindowsPrinterConnection "\\server\NRG_2500"

net.SetDefaultPrinter "\\server\NRG _2500"

Actually it is potentially as simple as adding another line:

net.RemoveWindowsPrinterConnection "\\oldserver\NRG_2500"

or whatever

Some more examples here:

Ok...thnx. I'll drop that line into the scripts, leave it there for a few weeks and see what happens.
Steve KnightIT ConsultancyCommented:
OK, give it a try and let us know, accept an answer when you're ready .... not chasing just 'cos I'm a few short of the 150k mark at all ;-)

It certainly works if the printers are previously installed from a server.  If they are locally installed ones then you run into issues such as the user not having admin rights to the workstation etc..

Good luck

A few more days to go yet so don't worry.

I added the line yesterday and will keep an eye open for results today, and post points as soon as I see the result.
Jason210Author Commented:
Well, I added that line last week, and when I checked today the printers are still there, unfortunately.
Steve KnightIT ConsultancyCommented:
Can I suggest you try it manually on one to see what is going on --  i.e. if you have a printer called \\server\oldprinter on a machine then add a RemoveConnetion to it's own little VBS script to see what it errorson if anything.  In fact are the printers installed as proper nework printers (printerx on servery) from a server or with a locally installed tcp/ip port?

Dim net
Set net = CreateObject("WScript.Network")
net.RemoveWindowsPrinterConnection "\\server\NRG_2500"

Jason210Author Commented:
Hi & thnx for the reply

The printers are installed locally on tcp/ip ports
Steve KnightIT ConsultancyCommented:
In which case... do the users have admin rights?
Jason210Author Commented:
of course not
Steve KnightIT ConsultancyCommented:
Or run it from startup script then I suppose if not actually... found some code here to do it.... will need the full printer name, i.e. HP Laserjet 4000N etc. as it isn't \\server\printer if it is locally installed...  if you ONLY want your new printers as maybe there are no local ones any more you could have this delete ALL local printers and then re-add your networked ones in your login script (just remove the where deviceid='xxxx' bit):


strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colInstalledPrinters = objWMIService.ExecQuery _
("Select * from Win32_Printer where DeviceID = 'ScriptedPrinter'") <-- Change ScriptedPrinted to the friendly name of the printer you want to delete

For Each objPrinter in colInstalledPrinters
Jason210Author Commented:
Thanks....but I asked a user just now to see if they could delete a printer connection, and he could, so I don't think rights is an issue. Or??
Steve KnightIT ConsultancyCommented:
Might not be a rights issue then in which case try the above in their login script.  The thing is if it is a locally installed printer rather than connecting to a server then the original commands just don't work, different stufff.

Jason210Author Commented:
ok thnx...

I'm sorry, but I misunderstood you, probably because I have to translate everything to and from Swedish. The printers are locally installed on tcp/ip port installed on a server, so everythings is spooled on the server. The connections are indeed shown as "printerx on servery" (C2500 på servern in Swedish...lol).

Sorry about that.
Steve KnightIT ConsultancyCommented:
No problem... someone did once teach me a few words of Swedish while I was in Goteburg but I don't think that would come in much useful here... it is fun finding your way around German / French / Japanese windows machines mind!

Anyway I'm surprised it doesn't work, fairly standard stuff.  What happens if you run the script manually as a user on one of these boxes.  Any errors?  I wonder if it is because the printer has been deleted, in which case it might be needed to add the printer back to the server again with the same name in order to delete it...

Another option is the old dll method:


rundll32 printui.dll,PrintUIEntry /dn /n "your printer name" /q
rundll32 printui.dll,PrintUIEntry /dl /n "your printer name" /q

Once you have one that runs manually whether an exe as above or VBS then add it to your scripts.  All have worked for me in the past so not sure why it doesn't work for you.

I never did figure out the problem...I just sent out memo to everyone instructing them to uninstall manually. It worked.!

I awarded the points because your answers seemed reasonable, and thanks for your efforts
Steve KnightIT ConsultancyCommented:
Thanks for the answer... hope it helped!

Steve KnightIT ConsultancyCommented:
Ahh as it happens looks like it didn't - we crossed posts there, thanks anyway then.
It's too bad - though I know a lot of people who have had trouble scripting the removal of printers esp. using the rundll32 method.
