I am running Linux Mint 13 with Cinammon. I have an old HP OfficeJet R40xi. When I try to print some document from LibreOffice or a pdf in "Normal Grayscale," the printing doesn't go through, and the job just stops. If I want to print in "Normal Color," the printing goes through, but my printer reacts badly when printing in "Normal Color" (pink everywhere), so I need Normal Grayscale printing. Draft Grayscale printing works, but the quality is not good enough.
I have CUPS and hplip both installed. I installed the OS very recently.
Thank you and hopefully you can help me find a solution!
