• The customer moved production cups printing from RHEL4 to RHEL5 , They are experiencing delays. The delays are seen mostly using socket back-end. They are defined as raw printer and mostly barcode printers. Further investigation has found that jobs wait for 5 seconds when using socket backend and since most of the jobs remain in queue delaying further.
