viewing micro sd card through printer

[asuri]

i have
micro sd card/adapter
Epson Stylus CX4200

i want
to try to revive/reformat old micro sd card that doesnt read on computer through r4 usb. i can put the micro sd adapter with card into the printer, but i dont know where or how to view/reformat the files. i tried using a working micro sd still cant find where the files are. all the manual says is print from the machine not comp. is there a way to reformat my micro sd card?
thanks in advance

When I insert cards into my Epson printer, they show up in Windows as if a flashdrive were inserted, and thus, viewable in the My Computer folder, at which point you should be able to right click the drive and select format
