Quick patch to send logs to a printer.

[Ben Clewett]

This is a quick patch which may be of interest to somebody: an addition 
to the standard Nagios log.

If you define PRINTER_FILE to something like '/dev/lp0', your logs will 
be echoed to that printer.  The date will be reformatted in human 
readable form on the printer.

So, after configure, in common.h, add:

#define PRINTER_FILE "/dev/lp0"

Ensure /dev/lp0 writeable by user nagios.

This is a good solution, as when I hear the printer working I know there 
is a new problem.  Much faster than any other method.

This is also ideal way of making use of an old dot-matrix wide carriage 
tractor feed printer, which most companies seem to have in a cupboard 
somewhere :)

Hoping somebody can make use of it,

Ben Clewett.
