In Devices and Printers there are multiple entries of the same printer.
This is a known Microsoft bug where the print server is added twice: one entry referencing the NETBIOS name of the print server and one entry referencing the FQDN of the same server in the registry key below.
HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider\Servers.
This issue can be created by adding the desired network printers manually and then restarting the Print Spooler on the affected machine and the printers will duplicate again.
It is recommended to contact Microsoft for an update regarding this issue.
