I'm running Ubuntu 15.10 with the latest updates as of 2 Feb 2016.
I use my laptop on my home Wi-Fi network and at at work on our school's Wi-Fi network. I have a Wi-Fi printer at home and a USB printer at my office.
I'd like to delete all the school printers that Ubuntu automatically adds to my list of available printers. I've tried to delete them, but they don't go away.
I've tried: System Settings > Printers > Right-click on networked printer > select Delete. The printer does not disappear from the list.
I've also tried doing the same as above, but pressing the Delete key on the keyboard. Still no joy.
I don't want to completely turn off Wi-Fi printing because I use that at home. I just want the printer dialog boxes to display only my own two printers.
