Description (hplip 3.12.10a-1):

While installing the printer, hp-setup restarts the cups daemon. It hardcodes the daemon script as either /etc/init.d/cups or /etc/init.d/cupsys, so the setup always fails on Arch.

[lines 120-131 in /usr/share/hplip/setup.py]
def restart_cups():
if os.path.exists('/etc/init.d/cups'):
return '/etc/init.d/cups restart'

elif os.path.exists('/etc/init.d/cupsys'):
return '/etc/init.d/cupsys restart'

else:
return 'killall -HUP cupsd'


Steps to reproduce:

# hp-setup -i IP_ADDRESS
