Printer disabled by scheduler

Adele Smith — Fri, 26 Oct 2001 05:28:45 GMT

Can anybody offer some advice on the following error outputed by the lpstat ???t command:

Disabled by scheduler: ERROR: Printer interface script returned non-zero exit status.

I have checked the log file that results from starting the scheduler in verbose mode in /var/adm/lp with no luck. There are no errors, the printer just disables itself a few seconds after being enabled.

Any help would be appreciated.

Thank you

Hi Adele,

If you search through the /var/spool/lp/interface/{printername} file, it should indicate the conditions under which a non-zero exit is returned.

Rgds, Robin

Adele,

Check the printer spool files under
/var/spool/lp/ .
The printer can get disabled if it
is not able to process the data/control spool
files of the printer which are pending in
the queue.
Every time a file is printed, two files- control and data are created in the spool directory corresponding to the request.
IF the control file has an error, the
printer will get disabled while trying to
process that request.

To confirm this, cancel the requests
of the printer. clear the /var/spool/lp/ directory.
Reenable the printer and send test printouts.

I have run into this problem, when a cranky
application software used to send errenous
characters in the print request.

HTH
