# cloudprint service for /etc/init.d/cloudprint
#
# Run cloudprint python connector as a Service
# Author: Gustavo Arnosti Neves
# System: Centos 6.5
#
# Cloudprint python connector:
#     https://github.com/armooo/cloudprint
#
# This script: 
#     https://gist.github.com/tavinus/e1062f66fe497fa4949d
#
# Cron checker script: 
#     https://gist.github.com/tavinus/494f42ff4b9436808ca6
#
# You should first run cloudprint as root from Bash to get a 
# Token/URL and link this computer to Google Cloud Print. After 
# the computer is linked you can use the Credentials file here.
# Just wait for cloudprint to finish installing the credentials
# and loading the printers. Then kill the cloudprint process
# and try installing/running the service.
#
# To kill the cloudprint process:
# sudo kill $(ps aux | grep "[c]loudprint" | awk {'print $2'})
#
# This init file requires the [daemon] install of the cloudprint.
# Just edit the variables below to set up for your system.
# You should run this as root (or you will need to change stuff).
#
# Use full-paths to files, or add a PATH variable or you will
# get errors.
#
# Check your Python and Cloudprint Paths with which:
# e.g. $ which python; which cloudprint
#
# Run on boot:
# $ sudo cp cloudprint /etc/init.d/cloudprint  # copy file
# $ sudo chkconfig --level 2345 cloudprint on  # turn on
