Hi, in photoshop CC 19.1.3 (problem started at 19, and on 18 does not occur), the print preview pane show/reset to wrong paper size after first print.
open an image, hit ctrl+p. select printer driver settings, set to any paper size.
the print preview show the exact paper size with image.
HIT print, (the image prints fine)
now, hit ctrl+p again (to print another copy)
and all the preview pane are messy. to fix, you need to open printer settings, Select another paper size, and the preview pane will be ajusted, after that you need to open printer settings again to select que correct paper size.
this does not occur on CC2017
