#755 Wrong default color model

[Alberto Salvia Novella]

I have a Canon Pixma MP280.

When I go to the printer options section, there are two options:

• Color Model
• Ink Type

These two options seem duplicates. Worse, they seem to have different incompatible settings by default.

Both shall be "CMYK", but "color model" is "RGB".

This makes the printer print wrong colors by default. Blues and reds shift hue due to not being represented in the correct color space.

Probably this affects more printers, but people aren't noticing this issue because they just assume the printer can't do better.

Can you please follow #757, I think this may be a dupe of that one.

It may be related, but it's not exactly the same bug.
