Only last subscription is being triggered

[edekeijzer]

I am trying to use this library to trigger two functions, one for job related events and the other for printer related events. However, only the last subscription I have made, is being triggered.

from time import sleep

def on_cups_printer_event(evt):
    print('Printer event')
    print(evt)

def on_cups_job_event(evt):
    print('Job event')
    print(evt)

cups_subscription.subscribe(on_cups_job_event, [event.CUPS_EVT_JOB_CREATED, event.CUPS_EVT_JOB_COMPLETED, event.CUPS_EVT_JOB_STOPPED])
sleep(60)
cups_subscription.subscribe(on_cups_printer_event, [event.CUPS_EVT_PRINTER_ADDED, event.CUPS_EVT_PRINTER_MODIFIED, event.CUPS_EVT_PRINTER_DELETED, event.CUPS_EVT_PRINTER_CHANGED, event.CUPS_EVT_PRINTER_CONFIG_CHANGED, event.CUPS_EVT_PRINTER_STATE_CHANGED])

Doing this (left out the cups subscription) it will trigger on adding and removing jobs for 60 seconds, but after that, it will only trigger on the printer related events.
