A second glass of Merlot. HP=extortion and I will not comply! The printer will stop working if any laser toner other than genuine HP toner cartridges are used (which cost 5 times as much as 3rd party toner); the HP mobile app will print documents, but only if they're PDF format. I'm a writer and use DOC files - I can't print them! Finally, there is no official Linux support so I can't even call their support line to figure out why my laptop can print fine, but my desktop can't print at all, even though they're running the exact same version of Linux. HP can stuff it. I like my old HP laser printer but it's simplex and I was really hoping for a full duplex printer... alas, that's not happening.
