Dashboard says Form3 is printing, Form3 shows a "Let's set up your printer the first time" kind of display

Walked in to check on my new Form3 printer and see how far along it was with the print. Instead of a usual printing layer # of layer’s info, I was aghast to see a display inviting me to set up my printer, as if for the first time.

Had the print stopped and been lost for some reason? I looked on Dashboard and it said the printer was still printing!

Hoping I would get lucky, I pressed cancel on the printer setup dialog. Then the printer showed me the print status I was expecting to have seen in the first place. It appears to be printing, the #layers is incrementing upwards.

Needless to say, this probably isn’t something that should have happened.
