Canon Community

I got a notice on my printer that a new firmware update is available. Every time I try to install I get - Cannot connect to server. Why is that?

I am currently running MacOS Monterey on an intel iMac and the Pro-1000 without issues. I am planning on purchasing a new Mac with the M1 chip. Any issues with the M1 chip and the Pro-1000? Thanks.

Why are these sliders grayed out? 

I have a Canon Pro-1000. I use Photoshop to print and my color profile is RGB. I print mostly on Red River Satin paper. Should I convert my color profile to CMYK prior to printing? FYI, the printer is fairly new and I am quite pleased with the colors...
