I installed an HP 3650 via HPLIP, and it works… well… sort of.
It only prints in blue, and will only print 3 pages of a 5 page document from a PDF (using KDE 4.0). Changing settings in CUPS, okular, and anywhere else I’m given the option has not fixed the problem.
Any idea? Printer is connected directly, so not networked or anything.
I had a blue printing issue in 11.0 some time ago now. I can’t say I really know what the issue was, but I did drop the HPLIP drivers and just used this method CUPS - Explained - openSUSE Forums
My problem did go away, however, at the same time I replaced my ink - so I was never totally sure what solved the problem.
