When I apply the printing command for printing the documents in the colors, my HP printer refuses directly to print the documents. I am not able to guess why my printing machine is showing this message? Really, I get shocked, when I saw this error message. It is very difficult for me to troubleshoot it. This case is very serious for me because I have to repair my printing machine immediately. I have tried my possible efforts, but no outcomes. So anyone can guide me for solving HP printer not printing color issue early.
