Following the recent firmware update/debacle, I now notice the B&W printing option previously located between 'Copies' and 'Two-sided' is no longer available. Is Greyscale the only option now?
OS Monterey, Pixma MG7520, iPhone 12When trying to print from iPhone the paper size changes from 'Letter' to '4 x 6 inches' after selecting the MG 7520 on network.
