When using CS versions of Adobe Illustrator and InDesign, you might not be able to print to queues hosted on Mac OS X Server 10.3.
At the client computer, the job appears briefly in the client printer window, then disappears. It doesn't print and never appears in the Queue listing of Server Admin or in the Print Service logs. However, it may appear on the server in the /var/spool/PrintService/<queue_name> directory.
To resolve the issue, update the server to 10.3.5 or later. You can get the updates here.
