Some print jobs sent to a Mac OS X Server 10.4 Print Server queue are not being recorded in the page log (/var/log/cups/page_log). If a job is not recorded in the page log, it will not count against the user's print quota.
For many printer models, you can resolve this issue by the installing the Mac OS X Server 10.4.6 update. If it does not resolve the issue with your printer, contact the printer manufacturer to see if an updated PPD is available. If not, set up the print queue using the Generic PPD instead of the printer-specific PPD.
For new queues, Server Admin will use the Generic PPD by default.
For existing queues with a printer-specific PPD, do the following:
Note: Clients should continue to use the printer-specific PPD in order to take advantage of the specific features of the printer not available through the Generic PPD. Using the Generic PPD on the server does not affect the client's use of printer-specific features.
