Ok, thanks!

(This is pretty much what I've found when I've looked for bins or trays,
which has confused me...)

Ah, ok...? So the PPD comes from the printer?  I didn't know that.  I
saw that the PPDs must be created from something, since all changes I
made to the file was overwritten, but I couldn't find a source for the
change.

Ok, /etc/cups/ppd before and it contained a .ppd file, and after the
printer had been switched off, /etc/cups/ppd was empty

Switched the printer back on, and the file /etc/cups/ppd/HP_Color_LaserJet_Pro_M252dw_501595_.ppd
was created:
 https://gist.github.com/steinarb/30c413c5a274472bcada19ddf6b4cf3b

I printed a test file, and after the print, the /etc/cups/ppd/HP_Color_LaserJet_Pro_M252dw_501595_.ppd
file looked like this:
 https://gist.github.com/steinarb/abdb46361d31db2918a692f51ff68ab0

The PPD as created just after switching the printer back can be found in
the first gist above, and the PPD after printing a test file can be
found in the second gist above.

Note: The test page was printed from the regular tray, and was not
waiting for a sheet to be fed into the manual slot.
