pycups-notify 0.0.2

Install

$> pip install pycups-notify

Usage

import time
import cups
from cups_notify import Subscriber

def on_event(evt):
    print(evt)

# Create a CUPS connection
conn = cups.Connection()

# Create a new subscriber
sub = Subscriber(conn)

# Subscribe the callback to all CUPS events
sub.subscribe(on_event)

try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    pass
finally:
    sub.stop()

It is possible to define a list of events on which the callback is binded:

import cups
from cups_notify import Subscriber, event

def my_callback(evt):
    print(evt.title, evt.description)

# Create a new subscriber
sub = Subscriber(cups.Connection())

# Subscribe the callback
sub.subscribe(my_callback, [event.CUPS_EVT_JOB_CREATED,
                            event.CUPS_EVT_JOB_COMPLETED,
                            event.CUPS_EVT_JOB_STOPPED])

If the CUPS server is not running on the same computer as the subscriber application one, the local IP address (same network than the CUPS server) have to be provided to the subscriber class:

# Create a CUPS connection
cups.setServer('198.20.34.1')
conn = cups.Connection()

# Create a new subscriber
sub = Subscriber(conn, '198.20.34.26')

Run

A simple listener can be started by typing the following command line:

$> pycups-notify
