Making connection to a web printer: "Filter" failed
What happened
When I tried to install Acanthus print system into my new MacBook Pro (Mojave), I could not find a window to enter certification information. Therefore, although I COULD connect my Mac to the printer, I COULDN'T print anything since error message "Filter" failed appered.
What I've tried
I've tried various ways such as:
Solution
Finally I found it. What I all had to do was to check Share this printer on the network
which appears in Printers&Scnanners window:
If this is on, a window to enter certification will emerge.
What to learn from this
Check your versions of applications and drivers to install before you push install
button.
