The printer didn't print anymore, already for several days. I was
called to fix the problem. Okay, let's see:

     univers# lpq
     e320 is not ready
     no entries

     univers# lpc status
     e320:
             printer is on device 'usb' speed -1
             queuing is enabled
             printing is disabled
             no entries
             daemon present

     univers# lpstat -p
     printer e320 disabled since Tue 23 Sep 2014 10:37:07 AM CEST -
             Unable to send data to printer.

The log file (/var/log/cups/error_log) told  me  that  there  was
some job that caused an error and thus stopped the printer.

First, I restarted the printer, quite easily, with:

     univers# cupsenable e320

Then I checked if everything was working again:

     univers# lpq
     e320 is ready
     no entries
     univers# lpc status
     e320:
             printer is on device 'usb' speed -1
             queuing is enabled
             printing is enabled
             no entries
             daemon present

To avoid similar problems in the future, I altered the policy  to
not stop the printer on errors but only abort the problematic job
(this probably should be the default):

     univers# ed - /etc/cups/printers.conf <<!
     /ErrorPolicy/s,stop-printer,abort-job,
     w
     q
     !

     univers# /etc/init.d/cups restart

Problem fixed. :-)
