The YaST sources are at
https://github.com/yast

The YaST printer module sources are at
https://github.com/yast/yast-printer
cf.
----------------------------------------------------
# rpm -qi yast2-printer | grep '^URL'
URL : https://github.com/yast/yast-printer
----------------------------------------------------

The YaST printer module does not implement
to do printer admin tasks as normal user.
The YaST printer module needs to run as 'root'.

The YaST printer module source code is generated
Ruby code which is somewhat readable but sometimes
it is hard to read (because it is generated code).

I would not recommend to deduce what to do from
reverse engineering the YaST printer module.

I recommend to Keep It Simple and Straightforward
and directly use the CUPS command line tools,
see the section
"Command-line Tools"
in
https://en.opensuse.org/SDB:CUPS_in_a_Nutshell
