[K12OSN] Ghost Printers

[Barry Solof <barry solof org>]

We are running K12ltsp version 5. 

The server runs one classroom of 12 terminals.  It ran flawlessly for 
months with one deskjet printer connected to a workstation.

When we added another deskjet to another workstation things got a bit 
weird.  Long story short, updating the server software fixed all of the 
issues but one. 

There is a phantom printer that still shows up in our users print dialog 
box.  This queue was deleted quite a while ago in the printer 
create/delete program (but it does show up as a recently accessed queue).

How do we get rid of the phantom printer/queue?
