Proposed patch

Description of problem:

This is the same as bug #432001 for enable/disable printer.

When a job with multiple files is in the queue when the printer is disabled, the job gets deleted when the printer is enabled again and the job is not printed.

Version-Release number of selected component (if applicable):

cups-1.3.7-8.el5_3.6

How reproducible:

100% reproducible

Steps to Reproduce:
1) Setup a printer:

  # /usr/sbin/lpadmin -p testprinter -E -v socket://127.0.0.1:9100 -m textonly.ppd

2) Create a few files to print:

  # echo "test print 1" > print1.txt
  # echo "test print 2" > print2.txt

3) Print two or more files by using the lp command:

  # lp -d testprinter print1.txt print2.txt
request id is testprinter-1 (2 file(s))

4) Make sure the jobs are still listed 

  # lpstat -o

  testprinter-483         ofourdan          2048   Tue 16 Jun 2009 01:38:36 PM BST

5) Disable the printer

  # cupsdisable testprinter

6) Make sure the jobs are still listed 

  # lpstat testprinter
  testprinter-483         ofourdan          2048   Tue 16 Jun 2009 01:38:36 PM BST
 
7) Re-enable the printer

  # cupsenable testprinter

8) Check for the job

  # lpstat testprinter
 
Actual results:

  Jobs has been de-queued, lpstat returns nothing

Expected results:

  # lpstat testprinter
  testprinter-483         ofourdan          2048   Tue 16 Jun 2009 01:38:36 PM BST

Additional info:

This is the same as bug #432001, the fix is very similar. Proposed patch attached.

PS: the bug seems to be present upstream too (at least in cups-1.3.10)
