Howto avoid that CUPS disable LPD printer

[Dario Lesca]

If I send a job to a LPD printer (lpd://printServ/port1) and if the
printer is off, after a lot of minutes CUPS disable the printer.
When I turn on the printer, CUPS not re-enabled it and I must run, as
root, /usr/bin/enabled printname or use http://localhost:631/printers whit administrative privilege.

Is possible to avoid the "disable feature" :-( ?

Or I must install a cron job witch every 5 minutes check if the printer
is disabled and re-enabled it?

Many thanks.
