When sending a print from archives that was previously sent to a different printer (same model, P1S) Bambu Studio gives a MQTT error and says "Please try updating Bambu Studio and then try again" (MQTT Command Verification Failed). The print file can be found on the printers device files, but no action is taken after it is sent.

It looks like this may impact any attempt to print from the archive, not only when the file was originally for another machine. On the screen of the P1S, we see "HMS_0500-0500-0001-0007", which matches the "MQTT Command Verification Failed" error we mentioned ealier.

Did you restart your printers after enabling developer mode? Who knows.... The error message usually means, that the dev mode is not enabled on printer.

Good call! Looks like it was our bad. Various people were setting up these printers and it looks like some forgot about developer mode. Made sure this was enabled and restarted them and now it seems to be running fine!
