Yep, since I've had this in December I've lost all ability to print anything with black ink. It's bizarre. And it's not just my printer, it's literally every printer I hook up to. I've talked to Apple multiple times and they've not helped at all. Just continually say it's the printer, but it can't be SIX printers. Something with my software/machine is just not right. Anyone else have this problem? Have a fix? Thoughts? Seriously, help. I'm a full-time freelancer, so I use my personal computer for business and to be unable to print is a real issue. Thanks!
