No more print jobs can be added.
Any action to correct the problem should be performed on that computer. The server does not have enough memory available to add another print job.
Wait a while, then send the print job again. If the problem persists, you may want to contact your network administrator about changing the MAXJOBS entry in the server's configuration file. This entry defines the maximum number of print jobs allowed on the server at one time. If the configuration file is changed, you must stop and restart the server's spooler for the changes to take effect.
