I must say this is very annoying, as this bug did not appear in earlier versions.
In Impress, when trying to print the presentation Slides 2-up (two per page) to a PDF file, the output is always to a Landscape page. Even though Portrait is selected.
Steps to Reproduce:
1.Create a multi-page Impress slide presentation in 4:3 layout for Slides.
2.Try to File > Print, and select "Page Layout" = 2 "pages per sheet".
3.Observe the onscreen depiction is in Landscape, even though the printer setup settings are all set to Portrait.
4.On General Tab, using "Properties" button, make sure that the selected printer is set to "Portrait".
The resulting PDF pages are in landscape layout, with the first slide on the sheet and the top portion of the second slide printed off the bottom of the sheet.
The page SHOULD be in Portrait layout, with 2 slides per sheet - one in the top half of the page, and one in the bottom half.

Good news for this bug is that I reproduced this in LO 6.2 (even with default 16:9. In my case, even if I set selected printer to "Portrait", next click shows it stayed Landscape).
But, good news for humanity is that I don't repro this in master 6.5+, with our new Print dialog that started in 6.3.
That general good is bad news for the survival of bug, which will be closed and sent to oblivion.
Should you, Reporter Robert, find all this different with your own test of Fresh LO 6.3.3, do not hesitate to explain in detail with attachments and restore bug back to life as Unconfirmed.
