My prusa won't print with 0.2mm nozzle

I've switched to a 0.2mm nozzle, sliced a model in prusaslicer with nozzle diameter set to 0.2mm and extrusion width to 110%. When i start the print my Prusa says that the nozzle diameter doesn't match the gcode, check settings. Then it cancels the print. The hardware settings only have 0.25mm... I've tried that but still the same thing.

How do I print with a 0.2mm nozzle?

The nozzle checks are just a "user convenience" feature. As @neophy says, you can disable it on the printer, or set it to warn only. If you are regularly printing with nozzles outside of the standard Prusa 0.25, 0.4, 0.6, and 0.8mm offerings, it's probably easier to disable the checks. You can also remove the check line from your startup code. These 2 lines at the top of the start gcode do the checks:

M862.3 P "[printer_model]" ; printer model check
M862.1 P[nozzle_diameter] ; nozzle diameter check

I just remove them and save a custom printer profile, but disabling the checks on the printer has the same effect.
