- Identify the printer make and model : HP Laserjet 4000 series
- Use the web or telnet interface on the printer to configure it for SNMP
- On a 4250, you can use the web interface under Networking Tab, Network Settings, SNMP
- Use telnet alternatively to set HP printer snmp settings Telnet <IP/Hostname>
- snmp-config 1
- default-get-cmnty 1
- (to enable trap sending) auth-trap 1
- trap-dest 10.129.92.52 (IP of zabbix server)
- Download the vendors MIB or a close proximity from MIB Depot and evaluate
- http://mibdepot.com
- Click the Search Option
- Choose Vendors on the left hand panel
- Locate and Select HP
- Search the web page for "Laserjet"
- Find the closest match "Laserjet Series 4200-MIB" and note the SNMP version is V1, however we will attempt to use Version 2c and will see that it works. If you don't get a return value try this trick.
- Browse the MIB looking for consumables such as INK and FUSER information. Fusers in HP Mibs are called Maintenance Kits for some models and Ink is sometimes called Toner or Marker Supplies so knowing the lingo helps.
- Identify the oid for a catagory such as prtMarkerSuppliesEntry .1.3.6.1.2.1.43.11.1.1.9.1.1 and note the tree structure (how the oid numbering is aligned and what other values are close to this one)
- Test the oid against the printer snmpwalk -v2c -cpublic -Of <ip of printer/hostname> 1.3.6.1.4.1.11.2.3.9.4.2.2.11.1.1 to see what is returned and disect the data

The first number should be the Toner, the second is the fuser. This is determined by looking at another A/V Pair under the prtMarkerSuppliesEntrydescription 1.3.6.1.4.1.11.2.3.9.4.2.2.11.1.1.6.0. The values 8.1.1 and 8.1.2 are the maximum capacity values when new toner and fuser are installed.
- This may be able to be confirmed from the web interface on the printer depending on the make, model and firmware on the printer.

- First check to see if an existing Template has been set up by someone else. If it exists, clone it for your use, if not create a new template and send a note to the list so that others will know it is there.
- An existing HP Printer Template exists so we will use Full Clone to make a copy for our use.
- Create a new snmp v1 item based on the OID identified in 2.c.xii above and set the polling interval for once per day or 86,400 seconds. For testing set this number low 60 seconds initially and change it later.
- Create 2 new triggers based on the OID to set an event threshold of < 500 pages for an action.
- Create a new action or adjust an existing action to send an alert when the threshold logic is true.
- Associate the template to a host that you wish to monitor
- Test the trigger by setting the comparison value to a one greater than the current value from 2.c.xii (7300) for Toner and validate that a page or email has been sent and that a status change is identified in the item.
- A graph can be created for the host to track the data that you are polling. Graphs can be configured to show triggers as well and both of these together can be helpful in diagnosing problems.
- Check your email or whatever notification service you set up to see if the trigger is working.
- If all the test work out, go back and set you polling interval in the template and the test value in the trigger to your permenant values. (86400 seconds polling current values and 500 pages for toner)
