I am following the steps described in this link:
it's no clear when it gets here:
<<Once you have changed all queues to WinPrint you could now remove the third party print processors from the cluster. However, think about the consequences before decide to delete them.
If a print queue is configured to use a print processor that no longer exists it will not appear when the print spooler is restarted. To get the queue back you have to edit the registry to change the print processor to WinPrint and restart the spooler. >>>
any expert out there to explain what they mean ?
