If Linux etc was easier to use , the numbers of users would be a lot more , end of day to many Distros and Sudo get this and that in the little black box , it will never catch on with the masses until it is made easier .
Utter rubbish. With our windows 7 & 8.1 computers & multifunction printer only the print function will work over the lan but the scanner and fax will only work with Direct USB connection. However the Linux computer works all functions over the network! Even HP said in their support website that network scanning & fax weren't supported in windows. The key to installing any printer in Linux is make sure it's on before you boot up the computer.
Linux and Ubuntu are ok if you have to much time on your hands , just try and get your printer working lol or simple functions , give it a go if you have to much time on your hands , ok for geeks or people that do not have a busy lifestyle. see you back on Windows soon .
No need for Unity. Use Ubuntu GNOME, Ubuntu MATE, Lubuntu, Xubuntu, ... without Unity. See all releases of the Ubuntu family.
