Public bug reported:
At home my cupsd daemon crashes all the time.
Sometimes I'm able to print a few pages but in most cases it ends-up
restarting and sending tons of crap to my printer resulting in multiple
wasted pages with non-sense characters printed on it.
I ended-up manually creating a core dump by launching it from root with:
# cupsd -f -c /etc/cups/cupsd.conf
(will attach core in post)
I tried using the default drivers for my printer then using the Samsung
provided ones with same result. My printer is a Samsung C460W.
Here is the systemd status:
$ sudo systemctl status cups
● cups.service - CUPS Scheduler
Loaded: loaded (/lib/systemd/system/cups.service; enabled; vendor preset:
enabled)
Active: failed (Result: core-dump) since Sat 2019-04-27 09:49:09 EDT; 12min

avr 27 09:49:09 eclipse systemd[1]: cups.service: Failed with result
'core-dump'.
avr 27 09:49:09 eclipse systemd[1]: Stopped CUPS Scheduler.
I wasn't able to find the core dump it refers to so that's why I ended-
up generating one by invoking cupsd manually then launching ubuntu-bug
against the cups package.
