hplip-plugin compatibility

Hey, I have a minor suggestion. Is it possible for the distro to distribute hplip-plugin so printers that aren't supported with just hplip itself will work? Or at the very least provide an ujust script for it? Currently I have to maintain my own custom image just to get printer drivers working which is okay for someone like me who is willing to put in the effort and knows how to do it, but this is probably a deal-breaker for someone who's less capable

hplip-plugin is hard to ship since it basically write the plugin at /usr

hopefully this can be added in the future using a sysext

Will also not work Hplip-plugin is not one package for all printer It downloaded the plugin for detected printer And then extract the plugin at /usr Which is dumb as shit holyfuck Why not just put the plugin at /usr/local or even better in user homedir 😭

It's very wack I have to rely on someone's gitlab which builds an RPM of hplip-plugin then install it via ostree and I automate it by making my own custom image, build the RPM there, then install the ostree

Hmm him wonder if this can be legally distributed in ublue image

Marcus LeeOP•2d ago

No clue lol, I'm not a lawyer

dreamyuki•2d ago

this obviously can't be distribute at copr repo since the plugin is proprietary

yeah

Here's a snippet from my containerfile if anyone's curious It's very scuffed but it works Some lines are commented because I don't use them anymore

Build an RPM in distrobox and then layer it No need for a custom image

Marcus LeeOP•2d ago

Hmm, if that's possible... I wonder if we can set up a ujust script for that
