A technician recently installed a new printer that is being shared over the network via a 64-bit Windows Print Server. Two users, who have computers with a legacy OS, are unable to print to this new printer. Which of the following should the technician do to resolve this issue?

While ensuring that the Print Spooler service is running is important for printing tasks, this action does not resolve the underlying issue of driver compatibility. If the correct drivers are not installed, enabling the Print Spooler will not enable the legacy OS users to print to the new printer.

Running Windows Update may provide updates for the operating system or other software, but it is unlikely to resolve driver compatibility issues with a 64-bit Print Server. Legacy operating systems may not receive updates that add support for newer printer drivers, making this choice ineffective for the printing issue.

Upgrading the users' computers to use 64-bit drivers is not feasible, as their legacy operating systems cannot support 64-bit drivers. This option overlooks the fundamental issue of the operating systems' compatibility with the Print Server and does not provide a solution for the users.
