When adding server printers to a Windows workstation using the normal GUI (add Printer), those printers are only available for the user who does the operation, which makes it kind of useless in most situation.
One workaround is to add the printer as a local printer, which the UNC name (\\server\printer) as the port name. However, this workaround does not allow to have the printer driver managed by the server.
However, another, better, workaround exists, from the DOS command line:
rundll32 printui.dll,PrintUIEntry /ga /n\\server\printer
sc stop spooler
sc start spooler
Thanks to Steve Clement for pointing out this workaround!
