    With a hacked JDK 9 (so that collate is not disabled) I can print
    either collated or un-collated.<br>
    This is on Ubuntu 16.04 with HP CP4525<br>
    <br>
    testing this is a pain since the spooler hangs in "processing" after
    every job<br>
    and I need to kill the process and restart the printer.<br>

    That is not a JDK problem since (a) outside our scope and (b) same

          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>

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

            The fix does not directly help the test. The idea is to have

                  so we do not look for collate-supported attribute in
                  CUPS. Infact, getAttMap does not have any
                  "collate-supported" attribute too!!<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>
