As mentioned in my post, Microsoft Dynamics GP 2013, Printer Selection, Named Printers, Page Orientation and the System Print Dialog, there was an issue where the feature to allow the printer destination to be changed after the report had been printed to screen did not honour printer setting changes made by Named Printers or the page orientation setting from report writer.
This issue was logged as Problem Report 68382: GP 2013 System Print Dialog ignores printer Destination provided on Run Report command (as used by Named Printers).
I am happy to announce that this bug has been fixed in Microsoft Dynamics GP 2013 Service Pack 2.
So now you can have printer selection cake and eat it too.
12-Nov-2013: While Service Pack 2 does fix some issues, there are still some other related issues with settings not being honoured. This is Problem Report 72319 and is scheduled to be fixed in GP 2013 R2 (SP3)
