I have the same problem with a Brother HL L2375-DW printer on Ubuntu 19.10.
This was auto-detected and added to the GNOME Printers as 'Brother_HL_L2375DW_series' - if I print double sided (long-edge) using the then it prints the second page upside down (as though I had selected short-edge) - but selecting short-edge also prints as short-edge. However, I then went into 'Printer Details' via the gear menu for the printer, and selected 'Select from Database...' and chose the 'Brother HL-L2375DW series, driverless, cups-filters 1.25' driver. At this stage a second instance of the printer appeared in GNOME Printers ('Brother_HL_L2375DW_series@BRW0C96E67E441E.local') - and printing to this second instance seems to work correctly. I am unsure how to know which PPD was used for the first auto-detected + added instance but if you can help me to find out I will happily attach the PPD here.
