Ah-ha!! I too have had this problem, and I as well thought it was a problem with the ink cartridge!
I am running Feisty and the problem still exists. I tried the above- linked package, provided by Pascal, as well. That didn't seem to help (although I didn't try rebooting or restarting any services; I'm not sure if that would be necessary). Does anyone know for sure where such a bug would live? Is it certainly / most likely in gs-esp? -- Fails to print black 100% on HP DeskJet 5150 printer https://launchpad.net/bugs/65568 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
