This is still broken in 3.11.10 (see comment #71). The hpcups driver gives over-printed blacks, using black ink *and* composite colour ink, with loss of quality/resolution in colour dithering.
Only the hpijs driver works correctly (tried "600 dpi, color, black + color cartridge"). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/235399 Title: "Print black" does not use black ink cartridge To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/235399/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
