Yes the cpp interface doesn't provice that.

Though as mentioned back in 2017 to Even, no one says what they really need, just the classes they hope we did not touch.

What we need is someone giving us the high level description of their needs so we can try to come up with the API they would need and we could maintain.

Also, I'll be honest here, lo-end Japanese printer companies are totally at the bottom of my list on "people I'd like to help during my spare time", so even if they gave me the best specification ever i doubt i would decide to work on that over the other 600 bugs we have.

But that's just me and we'd be still good to have such specification, once we have that spec maybe they could themselves work on it ;)
