Not printing in black and white

[oliviadres]

Hello, 

My Canon MG 3620 will not print in black and white, and I cannot figure out how to solve this problem. 

I am using a macOS Big Sur version 11.1

MacBook Pro (13-inch, 2020, Two Thurderbolt 3 ports)

Processor: 1.4 GHz Quad-Core Intel Core i5

I have tried to do the textedit solution, but do not have the option to click print in the file folder.

Hi oliviadres,

First, let's perform a test of your PIXMA MG3620.

Please hold down the STOP button until the Error light blinks 1 time, then release it immediately.

Please compare your printout to the example below.

Does your page have a black grid at the top followed by 2 blue, 2 pink and 2 yellow bars?
