The Cannon driver is the newest one, which is released on 11/09/17. I used
cngplpto correct print data including B/W.
After that, the printer works fine for 17.04. Everyone was happy.
After a while, Lubuntu keeps on asking me to upgrade to 17.10 ... I regret my decision.
Why the printer stops working now?
When I ask it to print something, it can connect to the printer. But it keep on "processing" the print job without actually doing anything.
Can disabling airprint help?
Please enlighten me with your wisdom before something very bad happens to me...
I think I might get killed because of this.
