My Printer Officejet Pro 7740 don't print format A3 in Color

[Erich10]

I have tried to print from my HP Officejet Pro 7740 format A3 in color but don't work properly, the pages printed coming out in gray scale but with very poor quality.

I put new cartridges thinking that the existing one were damaged but the problem is the same.
