I'm running Lightroom 5.6 on a PC with Win 8.1
When using the print module, I use PAGE SETUP to set the paper size. When I set A4 or A3 paper sizes, the correct dimensions are shown on the rulers in the layout. However when I set the paper size to A3+, the rulers show the wrong size of 21.5x28cm. Whereas A3+ is actually 33x48.3 cm. Can anyone help with this?
My printer is a Canon Pro 9500 MkII.
Looks right on my end with a Canon driver.
This might be one of those cases where a Preference File reset would restore the rulers for the A3+. Instructions here: Resetting (or 'Trashing') the Lightroom Preferences file - Lightroom Forums
Failing that I would be looking for an updated driver from Canon next.
I had my driver set as XPS and have changed it back to the standard driver and the correct dimension now appear.
