Printer: Canon Pixma Pro 10
CUPS is installed and running
Paper was 8 1/2 x 11 and 13x19 (A3+) Canon Pro Lustre
Margins were set in darktable, I’ve never known a way to set them in Turbo Print.
I’m not sure what scaling is so I will guess I’ve never adjusted it in either application.
I think it has something to do with the little black marks that show the non-printable area described here. I think I can set up the printer to be borderless but if I can’t, not knowing the measurements of the non-printable area means a lot of guess work trying to dial in the margins.
UPDATE: I can’t set it up as borderless.
