One page would print then 10 seconds later the next, so on and so on. Using a raw print que on server and a PostScript driver on the clients seem to work.

Avoid cups for a quick test: 2 ways: 1) get the lprng rpm and extract lpr and lpq to a directory, both should be usable even with little to no configuration aside the normal host printing setup. The nice effect: things like lprng -...@host just work, without adding queues, discovery and other annoyances. 2) just ftp the file to the printer (maybe newer jetdirect cards also support things like ipp / http as well?). The 2nd method at least reduces the components being tested to the raw network connection between two boxes. And of course, effects due to funny things being printed (testing with multiple printers and having one set of tests print a single file run thru gs to produce pcl-3 or higher may be a good way to detect funny postscript like strange font embedding (e.g. from the application/library/... on a badly configured client), or full color for a blackwhite laser, etc). -- cu Peter l Jakobi li...@kefk.oa.shuttle.de ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I'm not sure avoiding cups would be useful. The problem seems to be with cups getting the print jobs from the queue to the printer. Once the printer finishes a job, it takes cups about 15 seconds to realize that the printer is available for the next job. -- Bowie ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
