Description shawn oconnor 2005-10-18 16:18:58 UTC 
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.
Comment 1 Tim Waugh 2005-10-19 14:06:59 UTC 
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)
Comment 2 shawn oconnor 2005-10-19 14:51:22 UTC 
(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.
