Printer Alert Table
1.3.6.1.2.1.43.18.1
The prtAlertTable lists all the critical and non-critical alerts currently active in the printer. A critical alert is one that stops the printer from printing immediately and printing can not continue until the critical alert condition is eliminated. Non-critical alerts are those items that do not stop printing but may at some future time. NOTE: The above description has been modified from RFC 1759 for clarification.
