Hi,<br>
<br>
Thanks for checking that.<br>
<br>
The bit I don't like here is that the end-user can then no longer
ask for collation<br>
at all on Linux even though it has some chance of working on some
versions.<br>

This is the case even without my change and collate option is
disabled for PrinterJob. <br>
My fix (?) makes it disabled for PrintJob too.<br>

---<br>
In our cups class we were doing a cupsAddOption("copies", "2",..
and cupsAddOption("Collate", "True", .. commands (see examples
below). It turns out the the cups "copies" command was killing the
Collating if it set to 2. Like the orientation postscript/cups
conflict you need to set the cups copies value to 1 to get the
collation to work. The postscript file already knows its going to
print out, for example 2 copies. <br>
---<br>
<br>
We set NumCopies in the Postscript along with collate :-<br>
mPSStream.print(isCollated() ? " /Collate true":"");<br>
mPSStream.print(" /NumCopies " +getCopiesInt());<br>
<br>
So when we exec we also do "lp -# 2 .. " or whatever do set
copies.<br>
<br>

We are setting copies to 1 in

<br>
One thing is that, in my testing in ubuntu14.04 "collation" is
working and "uncollation" is not working. When I print 2 copies and
do not select "collate" option in printer dialog [I enabled collate
option by commenting out the isLinux check from
<a class="moz-txt-link-freetext" href="http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/unix/classes/sun/print/IPPPrintService.java#l1062">http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/unix/classes/sun/print/IPPPrintService.java#l1062</a>]
<br>
then, it prints Page 0, Page 1, Page 0, Page 1 [same as, when I
checked "collate" option] in my Ricoh printer in double-sided print.
I think for uncollation, it should print Page 0, Page 0 back-to-back
in 1 copy and Page1-Page1 in another copy, right?<br>

Regarding being hard-coded for "Selection", the point there is that in the AWT code path

I tracked down the changeset that has the code you reference

then it becomes clear (sort of) that this was a workaround for the oddity that Collate
worked on Ubuntu 12.04 but not on Ubuntu 13.04, so the idea was to stop saying it
was supported.
That is very annoying of course and I'd love to know if we've rechecked from the source that

Also the fix you are proposing doesn't seem to change anything that will help

The fix does not directly help the test. The idea is to have the
test call first isAttributeCategorySupprted(SheetCollate.class)
and only execute the test if it is supported. It is mentioned
inthe bug report.<br>
Since, now our code returns false for SheetCollate attribute, my
fix will disable the collate option to prevent anomaly of
returning false for support but enabling the collate option.<br>

<p>Hi Phil,</p>
<p>I was investigating JDK-8170352: The collate option is
not checked and I found that CUPS does not report
collate as supported attribute. <br>
</p>
It is removed from printRequestAttrib [<a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/unix/classes/sun/print/IPPPrintService.java#l167">http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/unix/classes/sun/print/IPPPrintService.java#l167</a>]<br>
so we do not look for collate-supported attribute in CUPS.
Infact, getAttMap does not have any "collate-supported"
attribute too!!<br>
Also, this code [<a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/unix/classes/sun/print/IPPPrintService.java#l1062">http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/unix/classes/sun/print/IPPPrintService.java#l1062</a>]
has been added [for 8016737] <br>
to remove SheetCollate from supported attributes.<br>
<br>
In light of this, I think we should disabled collate
option from our print dialog even for Toolkit based
PrintJob. It seems, from this code <br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/share/classes/sun/print/ServiceDialog.java#l1251">http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/share/classes/sun/print/ServiceDialog.java#l1251</a><br>
it is enabled if we specify in testcase<br>
<i>job.setDefaultSelection(JobAttributes.DefaultSelectionType.SELECTION);
</i>in which case isAWT set to true.<br>
even though selection is determined by attribute support [<a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/share/classes/sun/print/ServiceDialog.java#l1320">http://hg.openjdk.java.net/jdk9/client/jdk/file/a21bac70753d/src/java.desktop/share/classes/sun/print/ServiceDialog.java#l1320</a>]<br>
<br>
I could not find why it is hardcoded to setEnabled(true)
for "Selection". Do you know? mercurial history shows that
line from jdk7 and I could not find previous history.<br>
I think there also, we should check for "<span id="l1320">scSupported"
to enable sheetcollate? Anyways, "Selection" option is
not there in linux.<br>
Please let me know your views.<br>
