SNMP settings Shows the used protocol settings for this printer

Note! If you configure the specific SNMP settings then the specific set­tings overwrite the Global SNMP settings for this printer.

If you click on Printer specific you can configure which protocol should be used to contact the printer and ask for status information.

Individual SNMP settings for a specific printer

SNMP version 1 & 2c
It’s the easiest but an unsafe way to get status information about printer’s. To config­ure it you have to setup a community name for the printers which should provide the information. The same community name has to be configured at the ThinPrint Hub’s web interface (illustration Printer Monitoring below).
Printer and Hub will communicate in clear text.

SNMP version 3
This kind of protocol is much safer as SNMP version 1 or 2c. You have to authenti­cate yourself with user name and password. The password will be encrypted as MD5 hash or SHA hash.
Optional you can setup a privacy passphrase which is encrypted via AES or DES to provide such more safety (see the Global SNMP Settings tab).

Find Printers tab

On this tab you can search for printers in the Hub’s local subnet. Supported protocols for discovery are Bonjour and mDNS.

Menu Function
Checkbox Find printers enables the automatic printer search function
Checkbox Automatically add printers to the printer list immediately moves all found printers from the Find Printers list to the Printers list and marks the as 
Use Printer • shows the selected printers in the Printers tab
• Afterwards, these Printers are not displayed until they are deleted in Printers.
Hide/show marks the selected printers as hidden or cancels it
With/out hidden • displays or hides the marked printers
• hidden printers appear gray highlighted (illustration below)
Refresh starts the search function again
filter function to display only specific printers
X cancels the filtering

 hidden printers appear gray highlighted

Global SNMP Settings tab

On this tab you can setup which protocol is used as default when contacting a printer to get status information via SNMP.

You can select:

  • SNMP version 1 & 2c
  • SNMP version 3

 global settings for printer monitoring

Menu Function
SNMP version 1 & 2c
Community name
Default: “public”
Setup the community which should be used for printer monitoring. You have to setup this community name at all printers you want to monitor.
SNMP version 3
User name
user name which will be used for identification at the printer
Authentication type you can choose between 2 encryption algorithms
• MD5 (Use only for test purposes)
Authentication passphrase password which will be used for authentication at the printer
Privacy type You can choose between 2 encryption algorithms:
Privacy passphrase password which will be used for encrypting your SNMP queries
Save saves your settings
Cancel cancels the operation

Furthermore,  the hub can be configured as an SNMP proxy.

Activating SNMP proxy

This makes it possible to query the Hub via SNMP and in this way obtain the status information about all printers previously set up on it.
