Comment 14 for bug 1808581

Thanks.

Ok, there is no port 9100, so socket:// will not work. One lives and learns!

Looking at the error_log again all the filters complete successfully:

Search for "exited" and "normally".

All that cnijnet:/ does is transport what rastertogutenprint.5.2 produces to the printer. Perhaps the printer is unhappy with the input from gutenprint? I cannot test this.

I can only suggest you use the Canon drivers.
