I did same i.e.
normalizing make and model what the system reports and
normalizing make and model in the PPDs in the same way,
then some "fuzzy match" to get a list of PPDs
that "somehow match" the reported make and model
with some "special sorting" to put the "somehow best match"
on top of that list and
finally show that list to the user so he can select one.

In automated setup case the topmost entry of that list
is used.

I vaguely described that in
https://en.opensuse.org/YaST_Printer#Driver

By the way 1:
For my general point of view about
"Automated Printer Configuration" see
https://en.opensuse.org/YaST_Printer#Automated_Printer_Configuration
versus the subsequent section
"Manual Printer Configuration with the YaST Printer Module"
therein.

By the way 2:
In practice the current "YaST Printer Module" is dead code, cf.
https://bugzilla.suse.com/show_bug.cgi?id=1175341#c1
I wished those who make the decisions would finally let it RIP.
