[Printing] Under what circumstances will Printer.startJob(), Printer.startPage() return false? [message #490943]

In PaperClips I've always assumed that Printer.startJob() and
..startPage() would only return false under weird error condition e.g.
out of system resources or some crazy thing, so I've always reacted to
this result by throwing an exception up to the caller. The

I've had a bug report now, where if the user prints to a PDF printer and
clicks cancel then startJob() returns false. This is a totally normal
use case and I think I should just abort in response to a false return
value.

Could any of the SWT devs clarify under what circumstances these methods
would return false?

Thanks,

Matthew

startJob() and startPage() return false when SWT was unable to start the job or the page. On windows for example we check if the return code for StartDoc and StartPage() is less than or equal to 0. If the user has clicked cancel, I would expect one of these functions would fail.

Mac has a strange "Save as PDF" option in the print dialog that allows you to Save as PDF, then cancel the print job. Is that what's going on here?
