Lab printers like the Prusa MINI+ aren't on the network, so once you hit print, the only way to check on it is to walk back. printsim is a stand-in: give it the same file you gave the printer, tap Start when the printer starts, and it rebuilds the print in 3D in real time, with how long is left and when it'll be done.
