F4480 AIO misalligned black when printing in color

Asked by Pierre-Alexandre Goulet on 2021-04-25

I have a F4480 that I am trying to give a second Life to because I hate e-waste. On Windows, everything prints fine. However, there seems to be a bug in the HPLIP driver, because the blacks wont print alligned when printing in color mode. The issue is not present when using the "black only gray-scale" print mode.

I thought the issue was with my HPLIP version being too old (originally, I was using 3.18.12 that shpis with Buster, but I have upgraded to 3.21.2 and the problem persists).

See the sample test page enclosed.

I have tried 2 different black cartridge and to allign the cartridge multiple times, but to no avail. I am fairly confident it's a driver bug, because no issues with the Windows version and the problem is limited to the black cartridge when printing in color mode.
