serial-number – HP-LASERJET-COMMON-MIB

Object

scalar mandatory OctetString

Identifies the serial number for the device.  If the
SERIAL-NUMBER object is set by the user, then setting
the object does not need to be protected.  If the
SERIAL-NUMBER object is set at the factory, then the
SERVICE-PASSWORD object must be set correctly before the
SERIAL-NUMBER object is writable.  If this is a writable
object, the POS should indicate the maximum supported
string length.  If possible, encode the serial number in
a symbol set (like Roman-8) that matches the ASCII
character set and limit the characters used to ASCII
characters.
Additional information:
This value IS AFFECTED BY NVRAM resets, it is set to the 
default value of XXXXXXXXXX, when a NVRAM init is done.
