A problem has been encountered these days that printers on a Windows 2008 print server cannot be deleted. You can remove the printer from the device and the printer, then refresh it, and they come out again. These printers have long been absent, and the icons for these printers are translucent. Right-click the printer selection to see what is currently being printed, and you can see that the print content is still in the queue more than 1 years ago. However, none of the printed content can be canceled.
The workaround is to clean up the print queue. First, stop the printer spooler service. Open the C:\Windows\System32\spool\PRINTER folder and empty all the contents. Then start the printer Spooler service. Back to the control Panel of the device and printer, refresh, those translucent printers have disappeared.
