In that case, check out the manufacturer’s website and look up the manual for that specific printer. Also see of they have their own slicer software. As others have said, Prusa Slicer is a good one. It also has a web GUI that will let you manage files, monitor and start/stop prints.

Another tip, (especially if your printer is banished to the basement like mine) is to get a small web cam for your printer so you can watch for problems remotely.
