I bought a Brother HL-L2375DW a couple of years back specifically for Linux compatibility, and it did NOT disappoint.
- haven't had a single error
- has not refused to print a single time
- super quick, good quality, duplex
- using cheap 3rd party toner without complaint
- works perfectly from Linux
I don't usually like to recommend brands/products, but this is the exception. If you need a printer, and black and white is all you need, go for this one.
Thanks :) Ah, you mean this one?

I built that last year specifically for our paprika (capsicum? never sure what the English word is. Web search says "pointed peppers"? Not hot though).
The previous years, every time around August the twigs would be full of large, heavy, but unripe fruit. Inevitably, we'd get windy weather and a third of the twigs would break off. The soil in those pots is not very deep (15cm, ca), so the trellis needed to be able to stand on its own. I really like the outcome, no breakage last year :)
The original idea came from here: https://www.youtube.com/watch?v=wFWNV1V0x3o adapted for our situation. The twigs end up kind of laying atop the supports.
Oh, and throwing a plastic foil over it in February/March also worked quite nicely to create a make-shift coldframe!

Sure thing!

For the barrels, they were simply sold with the bases. Didn't see a reason not to use them, and also allowed me to drill the hole for the hose connector as close to the bottom as possible (used both for filling water in and for leveling between the two barrels, since the pump is only in one of the barrels, see last picture). I don't remember what the barrels cost exactly, but it wasn't too much and I'm happy with the sturdiness.
For the compost bin, we could have gone a bit more expensive tbh. This one was <25€, and as you can see, it's not exactly shaping up to be a paragon of longevity. It sits on some slabs that were already in that corner, and I though it might help drain excess water...? Not sure though, I don't think it does anything. The compost bin is also too small (and unsturdy) to go in with a shovel from the top and dig the compost over, which would really be beneficial. But still worth it. We put all our kitchen scraps in, almost completely eliminating residual waste bad usage for us, and I pull about 70l of compost out of it each spring.
If you have a place where you can place the bin in the garden rather than on the deck, dot it, I'd say. Take a look around youtube or something, there's some really cool composting systems.
Good luck! Hope the pictures help. Sorry for being so slow to respond.
