Error Code

HP ENVY 4520


My printer will only print in black and white and when I try to change the printing preferences, I get a protection error.


Please help!! I'm a small business and urgently need to print a customers order.

Error Code



Welcome to HP support community.


Which operating system is installed on the computer to which this printer is connected?



If you are using Windows 10 OS, follow the below steps:

I recommend using the gray-scale option to print in B&w, here are the steps:

Depending on your printer software there are two different methods to set grayscale and black ink only.

  1. Inside printer preferences you switch to the Features tab. Here you should see grayscale in the bottom left corner. Once grayscale is selected you may switch quality to black ink only. Then press ok.
  2. In printer preferences you click on the Advanced button. You should see a "Print in grayscale" option set to "Off" switch it to grayscale or black ink only and press ok.

Let me know how it goes.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.
