Well, I rebooted my computer and found out that before I had restarted the printer server I did these commands:
Then linux could see the printer.
But, I tried printing again and a bunch of ink was scratched on the paper in lines
. I did it again with various documents and the same thing happend.
I don't know what the problem was, but it wasn't the ink or printer because my dad is using it on his computer, and it's fine.
