Questions on the qidi plus 4

I have been looking at the Qidi line of printers for quite some time. At time I went with the BBLs, but with changes I will no longer be buying any more additional printers from them for the for seeable future. I have been watching development of Qidi and the newer line up of Creality printers and 2 years back they just did not seem quite there yet, but now seem much more evolved.

The new Qidi plus 4 I like how it can load the filament etc similar to the BBL and looks like infact improved in some ways. For an example the way it cleans it nozzle etc and the large build plate is a big plus as I need a large build plate printer at the moment for the farm. The current hypercube I built is getting very old LOL.

So here are a few questions, and thanks in advance to anyone answers to these questions =).

Can I print to the printer directly from Orca slicer to the printer if it is on the same LAN?

Has the SSR issue been fully fixed or just a software band aid? Are all the new units being shipped with the newer hardware fix? Does anyone know if you get one with the bad hardware if they are willing to correct it?

Is there a way to mount the spool lower instead of above the printer? (Will mess with shelving in the farm having it high like that.

Any features or issues you think I should know of?

I think that is all the questions and thanks again.
