Using esup-cups-backend

Setting up printers to use esup-cupsbackendÂ
Once esup-cupsbackend is installed (see esup-cupsbackend - Install and upgrade), the CUPS interface (http://your-server:631) should now present a new backend name ESUP-Portail when modifying a printer.
URIS of printers with the ESUP-Portail backend look like:
esup://<printer_ip_or_fqdn>?model=<model>&options
Available models are hp, lexmark, xerox, toshiba, dell, jetdirectNoAccounting, jetdirectGenericSnmpAccounting, jetdirectGenericSnmpAccountingPjlInfo (have a look at /properties/domain/domain.xml to add your own models).
Options :
- socketPort=<socket_port> (jetdirect printers only)
- lpdPort=<lpd_port> (LPD printers only)
- lpdPath=<lpd_path> (LPD printers only)
- ippPort=<ipp_port> (IPP printers only)
- ippPath=<ipp_path> (IPP printers only)
- pjlPort=<pjl_port> (PJL printers only)
Configuring the logs
esup-cupsbackend uses log4j for the logs, thus the logs are configured by editing the file /properties/logging/log4j.properties.
To turn on debug for the whole esup-cups-backend application, use:
log4j.logger.esup-backend=DEBUG
To turn on debug for a specific printer xxx, use:
log4j.logger.esup-backend=INFO log4j.logger.esup-backend.printer-xxx=DEBUG
esup-cupsbackend should be redeployed when the log4j configuration files are changed for the changes to be taken into account.
Using scripts
esup-cupsbackend provides basic scripts to monitor CUPS, all located in your install directory (usually /usr/local/src/esup-cupsbackend/current):
ps.sh prints a list of the currently running processes of esup-cupsbackend:
[root@server current]# ./ps.sh ****************** queue=ie016023 (pid=18978, start=11:18:29, user=26005200) printer is not ready (OTHER), waiting... - view printer status: ./test-printer.sh ie016023 - trace process: ./trace.sh pid 18978 - trace job: ./trace.sh job 69619 - trace queue: ./trace.sh printer ie016023 - kill all processes: kill -9 18978 ****************** queue=IE016099 (pid=24023, start=11:44:26, user=24002688) printer info: status=READY, counter=548884 - view printer status: ./test-printer.sh IE016099 - trace process: ./trace.sh pid 24023 - trace job: ./trace.sh job 69755 - trace queue: ./trace.sh printer IE016099 - kill all processes: kill -9 24023 ****************** queue=ie031098 (pid=16570, start=11:00:44, user=28003111) printer is not ready (OTHER), waiting... - view printer status: ./test-printer.sh ie031098 - trace process: ./trace.sh pid 16570 - trace job: ./trace.sh job 69554 - trace queue: ./trace.sh printer ie031098 - kill all processes: kill -9 16570
test-printer.sh shows the status of a printer:
[root@server current]# ./test-printer.sh ie024015 status=OTHER, counter=101415
trace.sh shows the last logs related to a printer, a job or a process:
