Why use licensed features, and what licensed features?
Without licensing, the print dialog will be shown and we do not know when
the print is finished, and hence when it would be safe to close this window
with script. Try printing the report without checking the 'Use licensed
features' option - the IE print dialog will appear, after being accepted a
'Printing has completed' message box will appear straight away and it would
be unsafe to close this window via script since the report may still be
printing.
You don't need a license. For example, in an Intranet environment, the
print dialog will not appear and if you know that all your reports are
printed within 30 seconds, a simple wait can be implemented in script.
However with
licensed printing, you can guarantee that the print dialog will not appear
and can also wait for the minimum amount of time required for the report to
print and guarantee that it is safe to close the window.
