(I must state that I am pretty new to Nagios, and there certainly is 
smarter ways to solve this - this is a simple way to check the printer 
status :)

I would believe that the print server reads the printers status from the 
printer via SNMP (?).

You will by this example be able to monitor the printers directly - not 
via the the print server as you asked.

One simple way to do this is using check_snmp to check the printers 
hrDeviceStatus.  In this query it checks for the return of two statuses 
Running (2) and Warning (3).  This states are considered OK to Nagios.

Warning is normally issued if the printer nags for a refill of toner 
(replacement not necessary yet) or for some printers when they need to 
change the waste tray.

10.10.10.10 is the ip of the printer.

check_snmp -H 10.10.10.10 -C public -o hrDeviceStatus.1 -r "2|3"

$USER1$/check_snmp -H $HOSTADDRESS$ -l STATUS -C public -o $ARG1$ -r $ARG2$

It's not necessary but I also ping the printers - it makes it easier for 
me to determine quickly if printer is shut off for some reason.

Just my 2 cents - hope it helped :)

If someone have a good hint on how to monitor replacement of toners on 
printers (mostly Canon an HP) I would be very happy - Is this printer 
specific? Do I have to check for each instance (one for black, cyan, 
magneta and yellow etc.) on each printer with different OIDs :O ?

Thanks.
