I have an older HP LaserJet 6P and have problems with the color of the font. Even though it is a monochrome printer and I select black as the font color from LibreOffice Writer or any other application, the print-out always seems to come out a light/medium grey color.
I don't think it's the printer because when I print from Winders applications, the output is fine.
I have CUPS installed and it recognizes the printer and installed the default driver (HP LaserJet 6p, hpcups 3.12.9).
I also have HPLIP 3.12.9 installed. It didn't see the printer (which is on a JetDirect), so I added it manually, but still didn't see an option to change the color depth or intensity (everything is set to the default setting).
Any suggestions?
