Description Tim Waugh 2010-11-09 13:05:39 UTC

Description of problem:
While investigating bug #595852 I discovered that the PrintServiceLookup.lookupPrintServices() implementation is not working correctly.  

Version-Release number of selected component (if applicable):
gcc-4.1.2-48.el5
cups-1.3.7-18.el5.5

How reproducible:
100%

Steps to Reproduce:
1. lpadmin -p foo -m pxlmono.ppd -v 'serial:/dev/ttyS0?baud=115200' -E
2. lpadmin -d foo
3. gcj -o test --main=test test.java
4. ./test
5. lpstat -s

Actual results:
4.
No printers available

5.
system default destination: foo
device for foo: serial:/dev/ttyS0?baud=115200

Expected results:
"foo" listed at step 4.

Additional info:
There is a suspicious comment in bug #618258 comment #3 as well:
==>
There is one differences: no printer I have supports
DocFlavor.INPUT_STREAM.TEXT_PLAIN_HOST, I I had to use
DocFlavor.INPUT_STREAM.POSTSCRIPT.  I doubt that this makes much of a
difference.
<==

All CUPS printers that support application/postscript also support text/plain.  This is because CUPS provides a filter that converts text/plain into application/postscript.

This makes me think that the PrintServiceLookup implementation is not correctly matching printer MIME types to DocFlavor types.

Comment 2 RHEL Program Management 2010-12-07 09:45:13 UTC

This request was evaluated by Red Hat Product Management for inclusion in Red Hat Enterprise Linux 5.6 and Red Hat does not plan to fix this issue the currently developed update.

Contact your manager or support representative in case you need to escalate this bug.

Comment 6 Tim Waugh 2011-03-18 13:42:19 UTC

More information about this problem is in bug #688480:

"When using Java's javax.print.PrintServiceLookup.lookupPrintServices
method, it returns an empty list of print services if the "Browsing"
directive in CUPS is turned on. If the "Browsing" directive in CUPS is
turned off, it works correctly returning a list of printers."
