OK, this didn't work. It seemed to work, but only because the app sat for a few
seconds before the next attempt to print. The print dialog reappears for each
window from which there was an attempt to print and cancelled. I found no
thread or hint on how to fix this. It seems to be related to garbage
collection, but it's not clear, if so, what to do in finalize. Even when the
previous window is closed, when trying to print, that previous window is opened
and the print dialog presented within. After a while though such self-reopened
windows fall apart, like list entries going missing and labels presenting no
more strings.
I tried:
forcing garbage collection in finalize
suggesting garbage collection in finalize
removing printed view from notification center, even though it has never been
made an observer
setting all properties of printed view to nil in finalize
cleanUpOperation in printOperationDidRun
The view's finalize method is processed, so it definitely seems to get
collected. Any help is greatly appreciated.

that should have been cleanUpOperation
