The check plugin printer_supply, which monitors the fill levels of printer supplies via SNMP, is now able to handle trailing null bytes in the field prtMarkerColorantValue (observed for example for HP Jetdirect 153). Previously, such null bytes broke the displaying of the corresponding service output in the GUI.
