774 Providing File Sharing, Mail, Collaboration, and Media Services Introduction to Print Services Without configuring managed print services, users will typically print directly to network print- ers by using the printer's integrated support for AppleTalk, IPP, LPR, or some other proprietary protocol, such as HP's JetDirect. This requires users to wait for the job to complete because their computer stays occupied spooling the print job to the printer. Any errors the printer encounters, such as an out-of-paper warning, are reported to the user to solve. There's also no easy way to keep track of or manage the jobs a printer is performing or a user is submitting beyond the simple page count recorded by the printer. CUPS With a print service running on the server, print queues can be established for each printer. Users then submit their print jobs to the server queue instead of directly to the printer. This enables end users to move on to other tasks or even put their systems to sleep while the server queue manages print jobs for them.
