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 spooling to the printer, 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 or are of very few pages, 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 spool and guarantee that it is safe to close the window.
