Dear Maintainer, After printing a file I get notification that document is sent to printer and then that printing is finished. The problem is that dbus notifier process stays alive after having done its job. Most probably the reason is that the process which calls the notifier does not close the pipe and the dbus notifier process keeps waiting for data to be read instead of getting EOF. Following are the outputs of "systemctl status cups" before and after printing a document. Notice the process list in the end of each. ● cups.service - CUPS Scheduler Loaded: loaded (/lib/systemd/system/cups.service; enabled; vendor preset: enabled) Active: active (running) since Sun 2021-03-07 15:44:27 +07; 12s ago TriggeredBy: ● cups.path ● cups.socket Docs: man:cupsd(8) Main PID: 5019 (cupsd) Status: "Scheduler is running..."
