I have an A4 single page document that I wish to print on A5 paper. This works on OO 3.2 but no longer works on 3.3.

Select File menu. Print...
General Tab. Click properties... button.
HP Laserjet CP1510 Properties dialog - select A5 page size and select "Print document on" A5. OK
Click Print button. Document prints at A4 size.
On going back to the printer properties dialog, the paper size has reverted to A4 and the "Print document on" setting has reverted to Off.

Note: I still have a PC with OO version 3.2.1 available. On this version, the document prints correctly scaled down to A5 and on returning to the printer settings dialog, the selected changes remain set.
