How to attach a different ppd toexistingprinter using CUPS API

[Azuri]

Model is actually the whole path to ppd file along with the name. What you mean by dropping ppd-name? removing the whole line of code?
  ippAddString(request, IPP_TAG_PRINTER, IPP_TAG_NAME, "ppd-name", NULL, model);

If so how will understand which ppd to attach
