I have a HP LaserJet CP1025NW (color) printer installed on a Linux Mint 20.1 machine using HPLIP (required plugin installed, version 3.20.11). For some reason, whenever I try to print a document (e.g. PDF, a text file, etc.) with black text inside, the text is always printed using the three CMY colors. The result is not as pretty looking as if the text had been printed using the black cartridge only; also, it is a waste of ink.

Notice that if the same document is printed via a Windows machine on the same printer, I get the expected result of black text printed in pure black.

I could not find any option (neither in CUPS, nor in HPLIP) to adjust this undesired behavior.

Any help is appreciated.

I eventually found a solution:

  1. Uninstall the printer from HPLIP and from the system;
  2. Be sure that the following package is installed: printer-driver-foo2zjs (I checked from Synpatics);
  3. Open http://localhost:631
  4. Add printer "HP LaserJet CP 1025nw (Hewlett-Packard HP LaserJet CP 1025nw)" from "Discovered Network Printers". Go ahead with installation until the last page with the "Add printer" button;
  5. Be sure to select "HP" from the "Make" menu (even if you already see "Hewlett Packard": they are two different "Make" items);
  6. Under "Model", select "HP LaserJet Pro CP1025nw Foomatic/foo2zjs-z3 (recommended) (en)" (be sure to find exactly that model: you have to scroll down quite a lot);
  7. Add the printer.
