There’s a more direct version of that, I guess from KDE, called KdirStat.

I hadn’t heard of the one in the op. But if I had to guess, it looks like it’s a different take on the same idea.

And I meant to say, most helpful resource for me was the website rtings. Most review and best of lists I can find by searching are so spammy, it’s hard to get any signal. But at least that one let’s me filter a table of printers by features. I just don’t know how many they’re missing.

Had to get a new one recently too. I’ve had good experiences w/ Brother in the past too, but couldn’t find one that quite fit the bill. Needed color and for it to be able to handle cardstock.

Ended up getting an Epson, one that’s in the eco tank line. Has been great so far. Works just fine out of the box on Linux (LTS Ubuntu, anyway)
