Read only file system

[fixit7]

When I used gimp to save a file to a SDXC UHS card in a slot in my printer, I got this message.

Read only file system.

I used chown to make me own with read/write permissions.

Is there a physical switch on the card?

It's set to unlocked.

I can write to the card when I use the card reader on my desktop. So I am good.

Maybe the card slot for the printer is designed to be read only.
