I take it to be the packages called 'cups*' in my current Ubuntu distro.

That is presumably just the ones that were installed.

OK, so it must be getting them in real time from a server somewhere.

These are the ones that are listed if I browse to localhost:631 and
click on Administration and go through the process and it eventually
lets you pick the make of printer (from Alps to Zebra) and for each one
it lists all the printers it knows about (for HP there are 3000 listed,
although many are alternative versions, eg 3.16.3 and 3.17.11, but it
includes three for the DeskJet 1510).

Thanks for clearing up my misinterpretation.
