You need to explain a bit more about what exactly this PR is for. “No description provided” is not acceptable.

Things need include:

• Function of this PR / what this PR implement?
• What change?
• Demo of the change

If this PR / functions for a specific printer. I don't think adding it to main repo is a good idea.

I don't think the printer specific function PR in to the main repo (mainstream) is a good idea. Since only that printer using this function.
It should be implement in your own repo (fork).

Yep but probably a part would be upstream.

Yep but probably a part would be upstream.

If a PR relate to a specific function of specific printer. That mean the printer require a specific repo to implement. The mainstream only focus the function that every device require.

I think they have a fork? If they don't and you want using the latest features. You should using your own repo to implement. If you add this into mainstream that main every printer using mainstream has this features.
