I can get all of them to print from Windows and Mac, but every one of them from HP, Brother, and some other brands could not print anything from Linux. They were all 'Linux ready' but were doing it via either Google Print or a set of proprietary software blobs to be put on the computer. [They even came with ipp filters but they called the blobs]. I have a Brother MFC-27100W in my office which I print to via my wife's Mac because of this. > Printers outside of your LAN need to be installed permanently right now > via printer configuration tools (CUPS web ui, gnome-control-center, > lpadmin) or via cups-browsed.

I've seen things you people wouldn't believe. Flame wars in sci.astro.orion. I have seen SPAM filters overload because of Godwin's Law. All those moments will be lost in time... like posts on BBS... time to reboot.
