1.Windows 2012 R2 print server
2.Users have Windows 7
3. deleted and recreated the print queue

When PC user double-clicks on the print queue residing on the Windows 2012 R2 print server they receive a message:

LoadLibraryEx error

And the Fiery print driver isn't downloaded.
If we need to use the printer driver utility, is this done at the individual users Windows 7 PC, or at the Print Server, thank you!!!!
