If it's not the cartridge and not the printhead, the driver may be the issue. We have one more solution to resolve HP Printer not Printing clearly. One way to fix the issue is to adjust the paper configurations.

To pick "glossy picture paper," try changing the printer driver settings as this may cause the printer to begin printing again. This only applies if there are two black cartridges in your printer – one based on the dye and the other pigment. Typically, the sort of black ink used by your printer would rely on the type of paper chosen. I hope your HP Printer not Printing clearly problem will solve. The black pigment performs best with matt paper and the glossy dye works. We hope to activate or jump any of the black cartridges to operate by changing from one type of paper to the other.
