You folks are missing the point, I think.  Read Scoop's message again.
He is asking the same question thousands of Macintosh developers have
asked before, "How do I change or override the Standard Print Dialogs?"
In this case, he wants the dialog to default to landscape mode.

The right way to do this would be a SetRotn opcode to the new
PrGeneral procedure.  Unfortunately, Apple forgot to implement
this.  I hope it was only a correctable oversight.

Apple's response has always been, "Don't do this.  Let the user select
the desired options from the standard dialogs."  Quoting from TN 122:

    Summary

    To be compatible with future printer-like devices, it is essential
    that your application print in a device-independant manner.  Avoid
    testing undocumented fields, setting fields in the print record
    directly and bypassing the existing print dialogs.  Use the Printing
    Manager dialogs, PrintDefault and PrValidate to set up the print
    record for you.

There is great virtue in consistency; I am certainly a big fan of the
consistent Macintosh user interface and regard the User Interface
Guidelines as gospel.  However, the lack of a programmatic interface
to the print manager is a longstanding deficiency.  In recent
TechNotes, Apple has sactioned methods to add to Print Dialogs (TN 95)
and added some further print manager functions (TN 128).  One of the
added functions is the GetRotn opcode to PrGeneral, which will let you
test whether the user has selected Landscape mode, after the fact.  So
the best you can do, if you want to be compatible with future printer
drivers, is put up a window saying, "Please select Landscape Mode"
along with the standard Style Dialog, and then issue an error or
warning message if Landscape mode has not been selected.

In my opinion, this looks like a real kludge to the end user; it's
confusing and it's unnecessarily time consuming.  The PrGeneral call
is a step in the right direction, but it's not complete.  Please add a
SetRotn opCode to the next release of PrGeneral.
