Background

I downloaded a handful of PPD files for Linux, with an expectation that they will work on TrueOS Desktop, which is currently based on FreeBSD 12.0-CURRENT.

I know that with the web interface to CUPS – typically http://localhost:631/ – there's 'Or Provide a PPD File:' with the option to browse the file system, but I prefer to have the driver listed after I select the relevant make/manufacturer.

Success, and the question

I experimented with placement of the PPD files at /usr/local/share/cups/model/other where the other directory was made by me.

Success (example below), but:

• I'd like to know whether a different path would be more appropriate.

Selecting a driver that relates to one of the four files that I placed at /usr/local/share/cups/model/other:

Using that driver, a print dialogue:

To answer your question: the directory you chose is Ok.

There is no other directory which is more appropriate.
