How can I obtain printer cartridges for this printer? The ink cartridges are PG-275 and CL-276. Canon has not been producing them and all online stores have been sold out for weeks. None of my local stores within 100 miles has them either. I bought a Tri color CL-276, but the printer will not print if the Black slot is empty or if there is an empty cartridge. Walmart advised me the next update is April 28th, 2022, but they can't even verify if they will receive these cartridges from canon. I'm to the point of returning my printer and purchasing a new brand with readily available supplies.
