I've done what you propose (unofficially of course :-) to read/set
the printer duplex setting. It does seem to work, but is not
guaranteed to be forward compatible. You'll have to walk down the
structure till you get the entry you need, modify it, and then put
everything back together.
I personally don't understand most of the fields either. I would just
concentrate on the com.apple.print.PrintSettings.PMCopies setting and
ignore the rest.
Some calls that will be helpful include PMFlattenPrintSettings,
CFDataCreateWithBytesNoCopy, ..., CFPropertyListCreateXMLData, and
PMUnflattenPrintSettings.
Also, I've seen Ticket manager documentation somewhere. Either on
Apple's website or in the Developer folder. Or maybe I just read the
appropriate header file. But it seems more geared to PDE authors.
When I tried it in my application, the calls didn't give me what I
needed.
Maybe you'll have better luck.

Dear all,
I am two months Macintosh/CodeWarrior programmer. I am working on a
project that needs to use Carbon-Printing manager. I failed to find
any document relating to Printing Ticket.
For instance:
OSStatus PMSetCopies ( PMPrintSettings printSettings,
UInt32 copies, Boolean lock );
This function is to set the number of copies to PMPrintSetting.
However, I know for sure that there is an alternative way to set
this settingvalue. That is to use TicketRef. It is something like
setting some ticket value to PMPrintSession in proper way. In this
way, we need to know the exact structure of such a ticket reference.
Actually, I printed out the structure of ticketRef, it turns out
quite complex. Some points I don't really understand.
<key>com.apple.print.PrintSettings.PMCopies</key>
<dict>
<key>com.apple.print.ticket.creator</key>
<string>com.apple.printingmanager</string>
<key>com.apple.print.ticket.itemArray</key>
<array>
<dict>
<key>com.apple.print.PrintSettings.PMCopies</key>
<integer>1</integer>
<key>com.apple.print.ticket.client</key>
<string>com.apple.printingmanager</string>
<key>com.apple.print.ticket.modDate</key>
<date>2004-12-24T02:11:29Z</date>
<key>com.apple.print.ticket.stateFlag</key>
<integer>0</integer>
</dict>
</array>
</dict>
Should I mimic the same this XML structure and then set to
PMPrintSession, shall it work ?
Anyone experienced this stuff please help me.
Thanks a lots.
Regards,
Bui Hung Viet.
