BUG: Print a A1 Layout at 1:2 scale at half size paper (A3)

Hi guys, I have an issue with printing a layout to scale. This is easy to reproduce so I won’t include a file.

Here’s what to do:

Set up a n A1 layout and assign the RhinoPDF printer to it (Or any other printer) and PRINT:
(All looks good)

Now set scale to 1:2 :

(Still looks good)

Then set paper size to A3 (Which is half of A1 in both directions)
And presto:

Rhino suddenly discards all info about LAYOUT orientation and focuses on the lower left corner.
Please change this to be center oriented for both settings.
