From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7 Description of problem: When sending multiple (10-20) small (1-2K) print jobs to a remote CUPS printer (epson dot matrix) via IPP using lpr, jobs print out-of-order, and intermittently duplicated. Problem does not occur when printer is connected to local port, or when lpd protocol is used. Version-Release number of selected component (if applicable): cups-1.1.22-0,.rc1.9.6 How reproducible: Always Steps to Reproduce: 1. Configure a local printer on a machine 2. Allow CUPS to discover it on another machine 3. Send 10-20 small print jobs to the remote printer Actual Results: Multiple test runs will produce different output order each time. Expected Results: Output should be identical. Additional info: LPRng does not exhibit this behaviour. Using lpd protocol with cups is too slow to be an acceptable workaround.
Thanks for your report. I would like to know more information: 1. What sort of jobs are these? PostScript jobs, or text files, or something else? 2. How precisely are you submitting the jobs? One long lpr command line, or multiple single-file lpr command lines? All from the same machine? 3. Does cups-1.1.22-0.rc1.9.8 produce the same behaviour? (See https://rhn.redhat.com/errata/RHSA-2005-772.html)
(A1&2) We're sending multi-line text-only print jobs with multiple calls to lpr. We've managed to reproduce the problem with a simple script - #!/bin/csh -f @ x = 0 set file="print.tmp" set printqueue = "fsp2" while($x < 25) echo "Print job $x" > $file lpr -r -P$printqueue $file @ x ++ end (A3) Yes, I tried upgrading to the CUPS in RHEL4U2; There was no change in behaviour.
