For the Sheet size, under the File/Titles and Sheet Setup there is a button on right side for Sheet Size. There you can select A4 and landscape.\
In the same File/Titles and Sheet Setup also (if not already ticked) click the boxes at the bottom for Display Titles and Display Sheet (borders) if you want a better final presentation.
By comparison with Martin57, my print preview on schematic comes up full size with scale 147%, print scale 100%, scale tables checked, scale to page checked (but scale to pages seemingly makes little difference.
Maybe as/if the printer type is already defined it makes some scaling assessment as the print preview scaling is not the same as the schematic drawing mode scaling.
