CUPS: 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 

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

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

Many thanks.
